  • ADC-4000 needing F1 board


    I'm in need of an F1 board to replace the now-departed board of recent demise!

    I would like to find a used one since I'm retired and on a fixed income .. sadly fixed low! ;-)

    Since I'm old and the organ is old, I really don't want to invest in a new and expensive part.

    I promise to give it a good home! ;-)

    Be sure to specify that what you need is the USFG-1 board. These are the original Frequency Generator boards for the first generation large cage ADC models -- 4000, 5000, 6000, 7000, and 8000 -- and these models only. Subsequent models used another FG board type, as did the small cage models (1000 through 3000). Since the USFG-1 was used only in this first series organs, it may be a little hard to find, but you are on the right track. I sure hope you find one. I'll keep my eyes and ears open here.

      If you can't find one, or Allen wants a fortune for one, I wouldn't rule out trying to locate an electronics expert who could try to diagnose it. Everything ADC era is easy to repair through-hole PCBs using almost all standard parts which would still be obtainable. Thought I doubt that partcular board has an electrolytic capacitors which are the easiest to diagnose. If it's an IC, that takes a bit more knowledge to sort out.

      My brother once needed some repairs to a pinball machine and found someone who was surprisingly cheap for doing PCB repair work though I no longer remember the details, I do recall it involved some replacement chips.
