D & M Restoration provides general repair or full restoration services for classic and vintage car radios from the 1920’s through 1980. 



Our general repair service for auto radios included the following items:

  • We service your tuner and push button mechanism including its adjustment and lubrication.
  • We align the AM and FM radio frequency, intermediate frequency, oscillator, audio amplifier and stereo multiplex circuitry after repair and replacement of defective parts.
  • We align the audio output bias voltages to the factor specified settings, clean or replace scratchy volume controls, install fresh dial lamps and buff and polish chrome and plastic dial plates.

If you have a unit with a Wonderbar type automatic tuning mechanism, we disassemble it to clean (including the speed governor mechanism), lubricate and adjust lever and switch trip points and clean relay and switch contactors.

If your radio uses a mechanical vibrator to generate its tube voltages, we replace the buffer capacitors, test the vibrator and replace it with a solid state unit as necessary to assure a long and reliable service life.

We disassemble your 8 track or cassette tape player, clean critical areas, adjust mechanical and electrical points and lubricate the unit.  We also change the physically and electrically leaking capacitors in the motor speed regulator, pre-amplifier and main amplifier stages and install new drive belts as needed.

In summation, we inspect every stage of your unit for correct operation!

Enhanced restoration services are available which include chassis cleaning, dial face reproduction and case painting.

Please contact us with your specific requests.

RADIO NEWSFLASH!

STATE-OF-THE-ART WORK
 
We have developed an auxiliary audio input module for classic car radios. With this device you can connect an iPod, MP3 player or any other device with a headphone jack and listen to your favorite music through your radio speaker system. Whether your car radio is an AM, FM, mono or stereo, you can enjoy a better listening experience with this D & M Restoration installed upgrade.
 
The module is a small electronic device that is mounted inside the radio and connected to the radio’s audio amplifier and power switch. It has a small diameter, easily concealed, cable terminated with a standard 3.5mm headphone plug. You simply plug the cable into the headphone jack of your iPod and turn it and the radio on. Switching between radio and the iPod is accomplished by momentarily turning the radio off then back on.
 
Some of the advantages of this method versus replacing the radio or a conversion is that the radio is kept original. None of the radios internal parts are discarded (as in a conversion) so if in the future you want to return the radio to its original state, it is just a matter of removing the module. In addition, it is significantly less expensive than replacing the radio or having it converted.
