wrote: Hello all, I've got 2 vintage Adcom repairs here that I need parts for. Anyone got any parts units around? One is a GFP-1A preamp that has a mangled input selector switch S4. The Adcom part number is PE-90386-02. It will NOT interchange with the record selector switch. Th original was mangled by a really bad attempt to clean it, and the contacts are bent and broken on one of the 2 wafers. The other is a GFT-1A. While I've got the service manual, it does not include the schematic. I've got a GFT-1 schematic, but it is quite different than the "A" version. This unit has a bad detector transformer T102. Sorry, no part number, as its not mentioned in the manual. Many thanks!, Tim Bristol Electronics Tim, Is Adcom gone or are they not supplying parts for their older models? Thanks. Chuck |

Chuck Chuck, I did contact the parts vendor Adcom mentions on their website, Affiliated Electronics in New Jersey. While I have no idea how extensive their parts inventory is, these units are 20+ years old, and they don't have them. Its why I was hoping another shop might have one in their junk heap. Adcom is still around, or at least they have a web site, but I don't know any local dealers that carry them. Regards, Tim |

I still rarely get some old Adcom pieces to work on and it is nice to know that Affiliated is still around. |

It's been 10 years since I looked into it, but my GTP 500 has a problem with the FM, no longer recall the symptoms. I was in electronic repair I know some products have a common problem. Is there an issue with the FM that crops up on this item? Such as C12 goes open/short? Mikek |

Replacing them requires a realignment, as you are replacing the things that you adjust to align the tuner. I would also not be surprised to see the memory backup capacitors failing by now. Regards, Tim Schwartz P.S. You are usually better off starting a new thread with a new header, as people who know your model will reply when they see it in the subject line. |
