Wayne Jackson of the Memphis Horns said "I was as talented as any one ever to step through the doors of 1700 Popular" Birth place of the Jingle industry.

One half of a comeback since 2005. The owner of a 63 Corvette WonderBar had to have unit back to make the big car show! Unit would stop on FM Converter but not up to factory specs. So i returned it to him while i searched for a parts donor unit.

In the very unusual event, You have a problem with a unit i restored for You! Your project goes to the top of my work list!

No matter what make or model GM car You have You are making money on my services! With a none working radio You loose value! With one of my RESTORED Delco units adding to Your vehicles! VALUE!

I can make vintage Delco Car Radios sound a 1000 times better than any found in 1958 to 1985 GM cars or trucks! Out performing most all top of the line sound systems sold today! Not to be out done by ANY!
the Delco stays factory with my hidden easy replaceable, update-able black boxes! That are true audiophile quality! Not cheap disposable ''JUNK!'' All modifications supporting these wonders can be remove taking the Delco back to factory set up, with NO TRACE of them ever having been there.

Before i start on the long ''NO'' list. Please IF You are wanting to send me work do not any any way HESITATE to send me an eMail or call after 2PM central time. I do want and will take time to talk with You about Your project.

BUT do not have time to help You identify a unit to sell on eBay [all the info i have is on the model# code page]
Nore to help one hook up a barn fine aka eBay unit to see if it works! Witch should only be done by a qualified tech.


I will NOT return a unit until i fell the:

Send or calling with a 'just checking on the progress on my project is coming does one thing: ""SLOWS DOWN SHOP PROGRESS" And, on Your project most of all!

After my Basic Electronic Restoration each unit receives at least two weeks playing time. More if they do not fell just right! For the E~Caps to seat. Unit to stabilize so rely-ability and, performance can be VERIFIED. Not assumed! Along with real world thermal testing of freezing, baking, cycling on and, off.

Not doing so leaves the door wide open for those dreaded ''COME BACKS!''
That i hate more than You do!

2012 In an effort to speed up turn around time on the 58~85 era units I no longer service the pre 1958 models. In the past 10 years or so. I have restored about 75 of these vibrator units. They consume a great deal of time because of my lack of expertise and, learning curve on them. The amount of parts that must be replaced in a Basic Electronic Restoration. With some parts only to be found in donor units and, the unbelievable price they go for now days.
I did enjoy the challenge of orientating my self to that era of technology but found my self forgetting about the weeks I was spending on them, losing jobs on 58~85 era units that i know like I know how to eat breakfast!

No Radios or Parts for sale!

NO FM conversions

NO Antenna repairs

NO tech advise outside of my restoration projects.

PLEASE! Do not send me a radio! Until I give You shipping authorization.

PLEASE! CONTACT me to check on my current work load.
I may have You ship unit IF i am working on other same model projects, or may ask You to reserve a place on my work list. By printing out and sending in this WORK ORDER with a $25.00 RSVP fee check. [fee will be deducted from the basic electronic restoration rate, but not refunded]
(((My goal is to work on units as i am requested to. BUT it is more productive to work on them in batches of like radios. The more of one unit i work on the more repeatable the work is. Then i do not have to think about witch way to turn a part to get it to fall into place, it just happens!)))


Please put a work order in with unit! when it is sent in. This work order is what i follow to restore You unit! I will remember nothing from a phone call or email so IF You do change work request keep reminding me of that change! OR it most likely will not get done!

If i have You send in RSVP or SHIP Give it time to make it into shop then send email. ALL EAMIL: WITH YOUR NAME AS SUBJECT. Stating that i should have received it. I will reply then save that email for further contact. When You ship use UPS tacking to follow Your project to my shop door.

If i do not confirm receipt of Your RSVP or SHIPMENT. Please send another email asking for it.

My electronic service skills come from going on my first TV service call with my Dad at the age of eight. Then growing up in his "BUD'S TV" shop in Alamo, TN. population 1900.

Certified and, trained by RCA & Motorola on there audio products at 13, Delco in 1967 at the age of 14.

I did not get Zenith's certification back in the day because they all ready had a TV tech in the area BUT i did do his audio work!

It is one thing to attend a training class offered by a manufacture Or work for them installing parts. BUT another to be CERTIFIED & PAID by DELCO to do there warranty work. i was the man? at the end of the production line that made the radios WORK!

In 1967 just as i turned 14 I was certified by Delco! The 43rd man ever to get such an accredation! Told i was the only one Delco found in a nation wide search through all the schools looking for "young ones" to train as there upcoming radio techs!

Amazed! my self! I was told that the golden age of radio was the 1930s `and, all the young ones of the day knew about radios was to go down to Walgreen's purchase a unit small enough to hide then use an ear piece in English class. They simply found know one else of my era even working in radio repair shops so they could be trained. Then started paying a not so bright 14 year old $125.00 flat rate for 2.5 hours on each unit they sent me. The Delco man said: "I was on my way"!

The next man on the list was 55 41 years older than i.

A few years later Dr. M.R. Bose was certified so i get to call him Jr.

I was told by the time i was 50. GM expected a 1958 Corvette to be worth $20,000.00 and they wanted to make sure there would be factory trained techs to take care of there radios!

Certified by N.A.P. on there digital audio products.

Working with the top of the line state of the art recording studio builders.

Live touring sound companies supplying equipment to the top music stars in the world.

50 years of on the job training in electronic sound system service! AND, I still learn on every unit i work on!

ALL of the Delco radios made before 1985 are long over due for their Basic Electronic Restoration! Many suffered from cold solder joints the day they left the factory! Age took out the Electrolytic Capacitors ten years later! even if it has been in a seald box sitting on the shelf! So that New Old Stock stuff is just an extra clean core, and lots of the NOS stuff never worked! If you want the radio in your Delco Car Radio to give the GREAT PERFORMANCES it was designed for and is capable of, then send it in for Basic Electronic Restoration! it is 30 to 40 years overdue for an oil change! Runing on FIVE plugs, with bad gas! and bald tires! Please do not subject your self to the Headaces of Psycho Acoustical Brain Damage that a sick radio is sure to cause!

I service all analog tube and solid state Delco radios made from 1958 to 1985 including the world famous signal seeking Wonderbar! With full pull out and instillation service at Your local GM dealer.

Basic Electronic Restoration SERVICE SERVICE RATES PAYMENT
Edison's Lost Lathe

Cleaning inside of radio with CRC degreaser. Cleaning & Lubrication of Volume Control, Push Buttons & Tuning Mechanism. Replacement of 8 Track Tape Belts, Lamps, Ceramic Fuses, Electrolytic Capacitors, Check & repair printed circuit board for cold solder joints. Hook radio up to a 600 amp 12 volt dc power supply, dummy speaker load, oscilloscope, signal generator, frequency counter & Simpson 260. Playing unit for two weeks testing and, repairing as necessary all of circuits. Thermal real world testing of freezing, baking, cycling on & off every 15 minutes for 24 hours at a time, checking for proper operation after each test. Tap with rubber hammer, bounce on bench 3 times several times.

The Basic Electronic Restoration MUST be done in order to tell what shape the radio is in, Once the Basic Electronic Restoration is done some radios will fail during playing ~ testing period making it impossible to tell what final cost will be! Until i have units fully restored ready for trip home. I have actually seen units start smoking when told they were ready to go back into the box and, go home!

Most all working radios from a driver car, will ship back at the basic rate. But some don't and their is NO WAY to KNOW for sure until I do the BASIC ELECTRONIC RESTORATION and they suffer my abuse for a couple of weeks.

A light clean up with GUNK & CRC CLEANERS, lubricate with Mobil-1 20/50. Cleaning & replacing only those components necessary to achieve as new electronic performance. Outside of dial face & chrome are cleaned and polished with NOVUS 1 & Q~TIPS.

I use original equipment manufactures parts if available, salvage as necessary, custom fabricate and, the lesser quality J-15 battlefield qualified military products if no others can be found.

My Basic Electronic Restoration is like doing a major tune up, to find a bad carb or fuel pump. They cost extra.

Speakers extra on all restorations.

RETURN SHIPPING $40.00 for: ''SIGNATURE REQUIRED'' UPS Ground with $1500.00 of insured value on a 12"X 12" X 12" box , 11 pounds or less, to Continental USA locations! IF You want Your project to be shipped as soon as it it in the box Please add $10.00 to cover UPS's scheduled a next day pick up fee or it will be shipped back the next time truck is at the shop. Witch may be a week or two.


Basic Electronic Restoration fee includes normal wear parts, mechanical clean up and, re lubrication, one phone call into shop, on a CLEAN CORE radio giving a FIVE YEAR WARRANTY on the radio not the owner. For LABOR & parts installed.

Please Note: Upon my first inspection I find that i am not going to be able to restore Your unit for the Basic Electronic Restoration fee I will notify You for approval to go ahead before doing any other work! If i see no obvious reason i can not do so I will proceed. Once You approve work. And, I do work there is no refund for that work.

Best to send in speaker(s) {even brand new ones} and, let me test them for proper operation. It would be a shame to service the radio, then have a speaker voice coil go bad taking out the output stage. Old tired radios also has an old tired speaker that cam with it. The new stuff has a 20-30% failure rate. AND, most new Corvette speakers have the wrong value loading coils witch damages the out put transistor.

No telling how may units are sent in with out speakers. Then I get this sad call with some one giving me this You ruined my life story. Me having a hard time convincing them to pull the speaker[s] to find half the cone missing from dry rot with a shorted voice coil. And they now have a bad out put stage in a just restored unit because of the bad speaker!

You may request the pointer, & dial face to be rescreened, cost depends on amount of work required. BUT: This could take $1000.00$ off the value of YOUR CLASSIC. If You do not state in work order You want the cosmetlogy i do not touch inside of bezel so dust is left inside just like she has never been touched.
Price can only be determined by the amount of work i have to do on Your unit.

Are avaible for many makes and, models. From .com vendors. TrimParts, CorvetteCentral, OPG, YearOne, etc or Google for others. Please order it and send in with unit for restoration. Waiting until I have Your project finished means i have to spend extra time retracing steps i could have done while i was doing the basic. Either way I will hang it for You and rescreen bezels along with dial pointer. Cost depends on amount of work required.
I do not need Your knobs and, had rather they not be sent with restoration projects. To clean them use a Q~Tip and, Armor All.

Studebaker use a glass lens and i can blow the numbers off waving a QTip at it.

Multi-Plex Adapters:

Many of my era AM/FM Mono Delco Radios are set up to work with a separate box to give FM~Stereo Operation. Some will have a shorting plug in the back, a round metal housing with a arm coming off the side with one screw holding it in place, multi pin connector some all in line some two rows of pins, that can be removed and a Multi-Plex Adapter plugged into the radio.

Others have the wires coming out of them and a connector on the Adapter for the radio wires to plug into.

Some of the Multi-Plexers have four knobs with unit mounting under dash so as to allow one to work the controls. Others are just a box hiden out of the way with wires and connector to plug into radio or connector for wires coming off radio to plug into.

Less than 7000 of the 1967 units with four knobs were ever made.

Multi-Plex Adapters were Delco first attempt into FM~Stereo very difficult to align and work on, many never worked from the factory! These units have parts only found today in other units and since the limited numbers madk these go for premium dollars today.

SPEAKERS: Speakers are not included in my basic fee. They are the tires of the sound system. They need to be checked with any Basic Electronic Restoration, Speakers are the most important and first part to fail in radios! Five years is about the life span of car speakers! Without the speakers that will be used i can only make a swag adjustment on the output bias. I see radios come in with no speaker, then when returned and installed i get spatic email or phone call saying "SHE DOES NOT WORK" finally the speaker is sent in and, their is nothing but metal left!

CORVETTE SPEAKERS: I see many output transformer on NEW SPEAKERS that are sold by big name Corvette vendors today that make radios run at a hand blistering temp You must WAKE~UP and check Yours for 1.5 Ohms across the speaker unplugged from radio. ANY THING LESS THAN 1.3 Ohms is to LOW! and is a ACCIDENT WAITING TO HAPPEN! Radio plays good for 15 minutes or so and then sound gets FUZZY. Real problem is what it does over time to the covering on wire feeding 12 Volts to the radio as well as the feed going to the radio fuse.

I have NO idea what speaker Your car needs! that info is best doctumented by measuring what is their now! Some are 3" deep and most any new speaker will fit. IN SOME CARS ONLY THE FACTORY 1.5" DEEP DELCO SPEAKERS WILL FIT!

New China replacement speaker in 4X10 & 6X9 size are $59.99 each.

New audiophle quality 6X9 speakers start at $99.99 each raw speaker,that do not include Sunshield, wiring, or . Corvette Loading coil.


Parts are avaible to restore these speakers: 3-1/4 inch mid-range, 4X6 inch used in kick panels, 5X7, 6X9X3, 6X9X1.5 & 4X10 inch speakers with a cone depth of 1-1/2 inch, 6X9 & 4X10 in the 3/4 inch depth. 6 inch used in the center of the back seat of some convertables. 8 inch used in the 1953 to 1957 models.

Reconing fees are $150.00 on all except the 6X9X1.5 used in 65,66,67 Corvette Air Conditoner models fee for the shallow cones 6X9 AC speaker is $175.00
Speaker baskets with soft parts that are dry rotted dust bowls or filled with other debris, have a minim $25.00 clean up fee added to reconing fee. The UKIER the debris the more it cost You! So take a wire brush and scraper and, put the junk in Your trash can! IF unit has a rubber gasket at the top leave it in place because it will have to be reused to seal off dash.



Factory 6X9 Delco Corvette speaker with loading coil. Corvette radios 1961 to 1967 must have a speaker loading coil of 1.5 Ohms.

The yellow aftermarket coil should be checked for proper impendeance of 1.5 ohms and are ''BAD'' untill proven good! I see a lot of them that are .25Ohm. With a load of less than 1.5 Ohms the radio will play fine for 15~20 minutes, then the radio OVER HEATS and, the sound becomes fuzzy! RETURN ALL NEW CORVETTE SPEAKERS with a coil less than 1.5 Ohms AND GET YOUR MONEY BACK BEFORE IT BURNS YOUR VETTE [maybe Your house or garage] TO THE GROUND!

My custom/hand wound Vett speaker loading coil is the best sounding one on the market today! An exact match to factory units! use with any 6X9 in Your 61~67 Corvette! $49.99

Delco Eight Track Tapes:

2103 saw many parts vendors dropping the drive belts form inventory! They are need regularly to maintain eight track tape players [about the same life as a set of tires]. Belt price have gone up 10 times over there cost last year. As they get at best 3 years of heavy use and 5 year shelf life they are all ways going to be need.

Delco stand alone T400 8 Track Tape Players switch the radio off when a tape is inserted use a one inch diameter X 1/8 thick switch that has 16 1/8 Amp contacts this switch, switching speakers and 12 Volts from radio to tape, gives lots of problems often causing both radio and tape to go up in smoke! Only way to reliable solve this problem is to use factory switch to trigger relays glued to the back of tape deck. With a fee of $450.00, $250.00 for the Basic Electronic Restoration and $200.00 for adding the 15 Amp relays.

While 8 trace tape players are fairly reliable with only the belts needing replacement as common maintenance item. They do need frequently cleaning of the tape path ~one bad tape can cause a lot of work~ and magnetic head demagnetized quite often.

Eight track tapes cartridges have lots of problems starting with the tape carts them self pulling the tape from the center of a closed loop, so they never worked that great in the first place. Along with sticky shed syndrome and, a host of age related problems today.
This is a great page on how to repair 8 track tape carts.

Normal wear of heads caused by the sand paper effect of tape passing over them, so units with high use, will need replacement of head or, outside of this shop relaping service that is not covered in Basic Electronic Restoration. The first test of wear is to drag a wooden Q~Tip stick vertical across tape path. IF a notch at top & bottom is felt, then excessive head ware is indicated. Result is increase of tape "HISS", poor tracking, distorted sound, excessive wear to the magnetic tape in the carts.


Please ship to me using UPS GROUND! In the interest of radio do not ship anything to me using United States Postal Service! AND in my interest please do not ship Fed X they come to early in the day! IF they wake me a 9:00AM and i just got in bed at 5:45AM my day is shoot!

PLEASE: IF You are worried about me receiving Your radio "REQUIRE SIGNATURE" for even more proof that i received Your radio! Track to me with there tracking system. After UPS has delivered Your Delco Radio please send me emails with Your full name first in the subject! (only one name per radio) "PLEASE" DO NOT CALL AND ASK "DID YOU GET MY RADIO" I loose work time when you call! 20 or 30 calls some weeks means no radios fixed!

Make sure to include every thing electronic that hooks up to radio speakers, output modual, rear volume controls, Many radios come in without output modual or SPEAKERS. I get a kick out of folks who do not send in speaker, then go SPATIC on me after reinstalling radio and it still don't work to finally send me the speaker for reconing and their is nothing but metal left!

SHIPPING DMAGED: radios that come into this shop most of the time have the shafts bent! and, are packed by SHIPPING STORES! do not trust them to know what they are doing! If taking a radio to them, PRINT OUT my way and give it to them!

Most radios with one speaker need at least a 12"X12"X12" box. It has just enough room for radio to fit in corner to corner with a soft ball size roll of bubble wrap in a plastic bag, taped to the front of radio! So it fells like You can bounce it off the floor, to keep shafts from damage. And well cardboard warped speaker. UPS ships at 11 pounds minim.

PLEASE! include a PACKING~WORK LIST [taped to a bottom inside box flap marked with a CIRCLED X on outside of flap] on a single sheet of "NEW" ~i use back side for work notes~ 8&1/2" X 11" paper With name, address of where radio is to be returned, email & phone number the first thing on page, then a BRIEF to the point as possible check list of work to be done! Any new items wanted such as speakers, wiring, etc. Along with a list of every thing sent in with radio! connectors, schematic, speaker, screws, etc that You expect to find in the box when radio is returned! Please state if You want cosmetlogy! or i will not do it! it is only factory once! This is the check list i will use for service & repack! I will not recall anything form a phone call or email so give me everything in this list in a BRIEF TO THE POINT as possible [here less is more! use the K.I.S.S. system] and make it readable! A 20 page print out of past emails is a sure way to cause both of us problems! I ship back ''SIGNATURE REQUIRED'' with $1500.00 of insured value. If You would like more insurance be sure to indicate so in packing letter and add extra cost to Your total.

Please put Your name on Radio, Speakers, any small items sent in. I do my best to check each box for small items. BUT it is possible for very small items to be missed IF just tossed into the box. Put all of the samlls into a plastic bag together and tape it to the radio. So i do not have to search through boxes to find all the items sent in. My time cost the same for working on radio or looking through box for a knob.

DO NOT SHIP: Radios with knobs on shaft! This increase the easy in getting them damaged and some volume control, tuning pods can only be found in parts donor radios. DO NOT SHIP: Radios with push buttons extend for resetting pointer location! While parts are a plenty, It takes several hours to replace push-button mechanics!

If You are sending in knobs for clean up or rescreening. Wrap in paper towels to keep them from scratching them self and bubble wrap and tape all together.

Mounting hardware KNOBS, bolts, clips, outside shaft nuts etc. I do not need and should be stored in a plastic bag taped inside the dash so they are there when You need them to re install radio. [Volume & Tuning shafts use two set of nuts each, one to hold shafts to radio ~leave bezel nuts in place~ Second set of shaft nuts holds radio to dash, keep these as i do not need them. IF You do not have 4 nuts ask for them on work order ~ ! Do not let shafts slide back into radio! Only using outside nuts can cause BIG PROBLEMS!!!],

~Shafts are what get damaged in shipping and cost BIG$$$~

REMOVE KNOBS FORM SHAFTS, COVER DIAL FACE, VOLUME/TONE, TUNING SHAFTS with a ''FIVE'' inch diameter tightly rolled roll of the bubble wrap, rolled as tight as You can get it, with the bubbles to the inside! tape roll so it can not unroll, place roll in plastic bag, slide radio's face against roll. Do not put tape on case of radio it is almost impossible to get glue off after it is on the case for any length of time.

DO NOT PUT TAPE ON RADIO CASE! TAPE plastic bag so bubble wrap roll will stay in place over front of radio then fill bottom of box with two inches of shipping peanuts, place radio corner to corner and speaker in box [12X12X12X If You need more room use two boxes of this size rather than one big box] and over fill with peanuts, shake down to pack tight. Seal all open seams of box with ample layers of tape to keep them from coming open in transit and loosing peanuts along the way!

This method of packing works much better than a one or two inch mummy rap, that is next to impossbe to get into and does not protect shafts in shipping!

Go online to UPS.COM or Call UPS to set up a one time GROUND pick up any where You like @ 1-800-742-5877 This is one of the listen and punch a couple of numbers depending on what You want to do to get to a human thangs.

NOTE just because You get a tracking # does not mean Your shipment is on it way back to You! I do not ship every day or week! UPS charges me $10.00 to scheduled a next day pick up AND unless You add it to the return shipping fee i will not do!

New China Replacements for most size & shapes of speakers used by Delco. Exception is the shallow depth 1-1/2 inch 6X9" & 4X10"units, only hope for these is to restore!

All of my modifications are reversible and use true modern day technology to enhannce the performance of Your DELCO! Yes they do use external black box best mounted out of the way in the trunk, BUT with 10 of your favorite CD's loaded in quick change clip (no djs or commercials ), and enough power to blow the back glass out of a Vette! or out blast SS396 side pipes! All set up with a neat factory type audio/wiring harnes for Your CLASSIC! Controlled by Your DELCO'S VOLUME & TONE You will wonder how You ever lived with out a HIGH PERFORMANCE SOUND SYSTEM!

Keep in mind the closer to as is the day it left the factory the more your CLASSIC is worth. In fact I was told by an auto appraiser that if the original radio is missing from a mint 65 Vett he would take $5000.00 OFF the value! That is why you will find that my J-15 service actually makes you MONEY!

Do not forget that nothing else will have that classic Delco Sound! Recording Studio Secret #1 "Make it sound good on a Delco Car Radio!". Yes ALL those great hits You love are cut to sound their BEST on a DELCO!!!

However if you would like a TOP OF THE LINE sound system! Here is How:

This is the first place to start, by upgrading the stock 87 db speakers & adding Acoustical treatment you will greatly improve sound quality.

I see a lot of folks pushing two 4 1/2" speakers mounted on a 6 X 9" base plate so that you have something to hook the extra stereo output up to, so it does not short out smoking the fuse. While on paper it looks good YOU loose all the bottom end and punch. Keep the 6 X 9" an add two silver dollar size twetters, You can silicone glue them to the windshield & they can be removed without a trace.

To get the best sound out of a Delco you need a Digital input! The easy way to Digital sound is by adding a mount anywhere R.F. CD player, They plug in original DELCO antenna port, and tunes in like a AM or FM radio station. Some hold 10 disc in a easy change clip, with extra clips available for long road trips. Trouble is they just DO NOT sound as good as a LINE LEVEL radio!

I can MODIFY DELCO radio FOR LINE INS & OUTS (RCA or MINI HEADPHONE connectors) this is simple wiring using original Delco electronic adding a few wires, that I make neat and clean.

For AM-FM radios feed line out audio from any devise with line outs such as XM Radio, MP3/Player that stores 150 CD'S that your load from your computer, or a trunk mount 12 disk CD JUKE BOX! Even a portable CD, Cassettie, 8 Track unit . Note: the devise You are using must have a line out! Headphone out is not the same. If headphone out is all Your devise has then a RF Modulator that broadcast into the FM band must be used. Not quite as clean as the line in BUT still the best station on the dial.

This feeds the audio form DELCO to power amps (POWER AMPS: Are the motor for sound system and their is lot of horse power {Watts} for the dollar now days!) with the DELCO'S Volume, Balance, and Tone controlling the sound! Feed the NEW LINE OUT of the Delco to as many POWER AMPS, EQ'S, DIGITAL SOUND PROSSERS & SPEAKERS as you wish! 1000 watts mono on the lows, 600 watts 4 channel on the mids (2 with 15 mil.sec of delay 2 with stereo flanging*), 200 watts for the tweeters. Now that will run with a SS396 in Mono and is gone in Surround Sound!

NOTE: Large Wattage power amp require large gauge power wires from the battery and, special wiring techniques to control noise click here to see my TECH TIPS page where You will find just is the best way to do so.
RMS is the true measure of an Amplifiers WATTS. Measured by taking an AC Volt meter measuring for highest AC Volt Value at the point of just distorting the amp. Say You get 10 Volts Multiply the Volts X them self. Say You get 10 Volts so 10X10=100 now divide 100 by Ohms of speaker 8 100/8=12.5 Watts.
Now comes the seals men side talk with IHF and Peak to Peak standers of measurement and. there valuer for Watts is doubled and triple of the real watts a amp is turning in a pro rig..

A lot of .comers offer adding a inside the case amp state 45 Watts taking the 48 Volt ratings of those amps, but in a car only supplying 12 Volts they are only 4.5 Watts witch is only one more than the factory Delco amp.

From the pro audio world, insert an ALESIS digital micro verb inline to a mid range 4 channel power amp, adding about 15 mill second delay on one pair of the mid range along with some stereo flanging on one pair of the mid range speakers. This will turn a MONO radio into Surround Sound & LETHALIZES! Stereo. Now you have a sound system WORTHY OF A CLASSIC with You sitting on the drummers throne so, "CRANK IT UP!"

The sound system will get more attention than the Car!!!

I do not rebuild power antennas.
Always a source of problems! Tune radio where their is no station Turn radio up about to about 1/3 volume tape mast with plastic end of nut driver if crashing noise is heard then mast is dirty or bad. Shake lead wire and if loud noise is heard then wire or connectors are dirty or broken.

The connector at radio & mast must be cleaned and checked for broken wire.

If your DELCO WINDSHIELD ANTENNA radio suffers from wiper noise (static electricity) clean windshield with DAWN and then apply RAIN X and, install new wiper blades if necessary. It is static electricity, from the blades across the antenna. I like these cause they keep the mast clean.


As NO reliable made to fit kits are made to do this, my advice is to forget about trying to cram a FM turner into the radio! Instead leave radio factory go with an external AudioVox FM Converter that was made in the late 60's and early 70's. I no longer sell these but i do still restore them for $50.00
They are 1"X4"X4~6" The best FM reception of any Mono FM turner i have ever found. Simply unplug the antenna form the radio and plug into the antenna port of the the FM Converter and then plug the antenna wire from the Converter into where You just removed the cars antenna on the radio, hook up the fused wire to +12Volts DC, tune the AM radio to 1400 and tune in the FM stations on the converter all You have to do to go back to AM is turn the volume down to save Your ears and push one button on the Converter.


This notion of converting a mono radio to stereo sounds great BUT the only kits i have ever seen to do this are nothing but JUNK!

Have seen a few conversions where someone went to WAL~MART and bought a $35.00 radio, gutted the Delco and crammed this JUNK inside KEEP IT DELCO!
From 66 until some time in the mid 70s when Delco went to a one peice Stereo unit Delco had two radios an all MONO unit and a [better sounding] unit that was sold most of the time as a MONO unit BUT had a round shorting plug in the back that could be removed and an optional black box STEREO MULTI-PLEXER ! plugged in that had the second channel of audio in it. Since most of these radios were sold with out the plexer the stereo light is not seen unless it is on [making it impossible to tell witch unit You have with out checking model # or for the shorting plug.] Because the plexer units were LOW preduction # add ons, kinda hard to find now days, VERY difficult to find parts for and even more difficult to get to work right, I charger $350.00 just to do the plexer.

IF You must have stereo [so You can brag to the guys at the water cooler] my suggestion is to get the factory Delco Stereo set up! IF You want GREAT! sounds [so folks two blocks away turn to see what You got going on!] use the MONO radio with my line out added to drive a 200 Watt power amp along with some great speakers!

Delco's electronics DESTROYED and new throw a way "JUNK ELECTRONICS" [with a hart stooping 44 watt amp IHF not RMS witch is really 4 watts] Installed inside case. I see Delcos destroyed and this worthless junk installed! Why? Because they can not repair the DELCO. Ask those who push this "NONE SENSE" were will You NEW DISPOSABLE ELECTRONICS be in 5 years if it works at all today? (same place a bic lighter goes when it quits.)

The turner in the DELCO will lock onto stations that the new ones skip over. .37RMS watts of power is the only real improvement. Yes .37 just over 1/3 of a real watt!! Compare that to a 600 watt Stereo power amp that YOUR DELCO'S VOLUME & TONE CONTROL DRIVES! by adding a line out {that is as clean as any audio there is! Not using the dirty speaker level output transistor}! Now go ahead and Drop in an additional 1000 watt mono blocks on the bottom end, a 600 watt~4 channel for the mids, along with a Digital Reverb & 400 watts for the top end IF YOU want a REAL stereo worthy of a CLASSIC! Plus the Delco is the same as the day she left the FACTORY with a few REVERSIBLE MODIFICATIONS, performed by THE ONLY DELCO CERTIFIED RADIO SERVICE TECH for the 1958 to 1975 models!

New modern day electronics? ALL analog transistor circuits are covered by Bell Laboratory patents of 1938! No amp in any auto sounds as good as does the 6V6 tube used in the 53,54, Corvette radios!

IF this "NEW MODERN DIGITAL ELECTRONICS" is so great. Why do recording studio engineers run it through "TUBES" to make it sound "GOOD"?

IF the front speakers are in the kick panels no matter what You do they are are not going to sound very good at all cause the air from them never gets into Your ears!

Tony Mac's Work History:

I went on my first TV service call with my dad at the age of eight, was certified by RCA & Motorola in 1966 when i was 12, in 1967 Delco certified me as their 43rd car radio warranty stations, I had just turned 14, 35 years younger than the next man on the list.
The skills gained in my Dad's T.V. repair shop have taken me into the Pro Audio world , designing & installing equipment in several multi million dollar recording studios.
Working with top stars like Mell Thillis, Sally Kellerman, Krystal Gail, Georgia Satellites , Ray Stevens, Tom Jones just to mention a few along with sound engineers from the Who, Phill Collins, Beach Boys, Linda Ronstat, Little Feat, Willie Nelson, Paul McCartney, and many many more.

I fell that their is no one that can match my passion and ability to RESTORE the 1958 through 1975 Delco radio.

I started working on these radios in 1966 while in the 7th grade & it was two years with my Dad telling me what to do before I realized what I was doing. I fixed at least 300 Delco radios in 1968! one year before i got my drivers license..
