I am still using mine. Largely as a line preamp. one of the phono pre channels is out. I too am looking for a good tech to fix it. since the PCBs are modular, the phone section can be pulled out and sent for repairs.
Curious if you still have your Accuphase C200-X pre-amp?
If so are you using it, have you had it restored?
I still have mine and searching for someone good to restore it.
