I can repair many makes and models of GM radios from 1970's until 1996 or so-just message me with any questions. Your radio will be serviced/rebuilt by a Delco-Certified professional with over 30 years experience; that is to say a GMFACTORY-TRAINED individual, NOT a "learn-as-you-go" paraprofessional!! Your radio will be disassembled, repaired, cleaned inside and out, adjusted and lubed; ALL repairs are done at a professional radio repair shop here in San Antonio and repairs include, but are not limited to the following: re-soldering points on the circuit board (a common failure of these producing no sound in specific speakers), capacitor check/replacement, illumination bulb replacement, AM/FM alignment, voltage checks to amps and audio modules...cassette service includes new belts, demagnetizing the head, capstans and/or pinch rollers replaced or cleaned and the speed of the tape will be correctly adjusted.
Having an original factory radio installed will not only rise the value of the car, but it will also score extra points when being judged at a show. These older Delco GM radios are becoming very hard to find, so if you are looking repair your desirable digital ETR AM/FM cassette equalizer stereo radio, this may be a good option for you, especially if your unit is in great cosmetic condition, You simply ship the radio to me along with a paper stating the issues you are having and a good contact number/address and I will ship it back to you after the repairs have been completed; shipping will be via FedEx, UPS or Priority Mail and your unit will be FULLY INSURED against loss or damage. Your radio will be shipped with USPS 2-3 Day Priority Mail, and can also be shipped worldwide using the USPS International Priority Mail service.
AGAIN, Although eBay provides only a 30-day warranty, I will personally provide a 1-year warranty on any radio repair you purchase from me.
