Little history about me: I start this business in 1990 using audiomart trade classified for buying selling and trading, it came in mail back then. I was on and listed in audio and sound bluebooks. I know many mod companies, techs and engineers with many manufactures. I have owned over 500 pieces of equipment and cables. My company also makes handmade cables. I do take partial trades depends on what it is and what buyer wants. good luck I have had quite a bit interest as I usually do, been on eBay since 1998.

ADCOM GTP-400 TUNER/PREAMP, Parts or Repair Excellent front panel  and very good physical condition. Unit does not power on. The fuse is not blown, but when I opened it up, you can see 2 or 3 parts that must have burned out and were removed on the motherboard. See the picture. The rest of the circuitry looks fine. You will need to download the schematic and parts list in the owner's manual on the web and replace these parts. Or, it is a Treasure trove of Adcom Parts worth many times the price. Sold As-Is.

Adcom GTP-400 Preamp Tuner Tested Works. Used. Standard ship. Stereo Tuner Preamplifier (1988-89) - Controls and switches cleaned. What I like most about this preamp is that you can use it as a dedicated headphone amp with a main amp. Yet as a preamp for one of your Adcom amplifiers it is just as good. Technicians arebig fans of the sound you get from Adcom preamps for the price. Tested FM and AM - both work. FM< picks up stations and locks in on stereo. Phono also sounds good. Some marks and or scratches yet presents well.
