Image may contain: indoor

Auxiliary input is standard!   This picture shows the optional Pre-Amp outputs, highly recommended if your audio system has to compete with your car for high levels of sound, such as convertibles, muscle cars, side pipes etc.  With this feature you can add as much power as you need!!  If your old like me, maybe it's not loud enough! 

Some radios have inadequate power on and off switches, 60's GM, Ford, and most Mopar radios have 5 amp or less current handling, for these radios we have to add a power relay that can handle currents up to 30 amps, for these radios ADD $25.00 INCLUDED!

8-Tracks will be quoted seperately, and will take more time,..years,... be prepared with lots of extra parts, or radio cores!! 

Can be programmed for North American or European channel spacing!

Can be configured to use the original (100 ohm) faders if available!

12 VOLT Positive Ground Systems

Add $100.00


6 volt electrical systems cannot provide 180 watts! 6 volt radios can be converted with reduced audio specifications. They should not drive more than two speakers. If your radio will be operated on a 6 volt system, add $100.00.

+ repairs to original components of the radio that are still needed and utilized by the new circuitry.

+ any extra fabricating or customization beyond the original radio case, face, special functions or controls,...etc.

Outer case reconditioning, missing or damaged components will be quoted after evaluation.

Please send us a nice radio that you would like to have back in your dash, we do not offer restoration/reconstruction services, rechroming & etc, if you need to get a better radio core, shop for one on E-Bay, most of the time it is a whole lot cheaper than trying to salvage a junk radio.  You will be happier, and we will be many times more happier!!!  Chrome polishing service is available at $50.00 per hour, and restoration if needed can take up to 3 years to complete. :)  Save time,.. don't send us the worst radio that you have off of your shelf to us!  Don't send us junk!
