Hi folks. I have a Sansui 9090 I am working on. The previous owner bought it from Noah Schumacher (of Hallo-Fi and Jahrgang Audio fame) as fully restored. It worked for a while then stopped working. He brought it back to Noah, who charged him to restore it again, but instead took 7 months to repair it. When the guy got it back it had a bunch of different lights and bent pots and he suspects that it's actually a different unit. Seriously. Anyway, it worked for a while and then stopped working again. So, now I have it. The 9090: Comes out of protection fine. Amp section works fine with the jumpers pulled. With the jumpers in, comes out of protection, but no sound and the FM tuning meters will not move at all. I am guessing no power to preamp/tuner sections. Here's what I have noticed as far as hackery goes: Rear AC fuseholder disconnected completely--no fuse in it and wires are cut. Unit still runs, wires appear to have been rerouted. This seems unsafe, right? Rear voltage selector was set at 100v, which seems bad. I changed it to 120v. The board with the relay has some badly damaged traces that were jumped. Relay and main caps are original, despite this being "restored" twice. I checked voltages coming out of the power transformer into the power supply and they appear to be good. I am guessing that prolonged operation set at 100v probably fried something in the power supply. Anything I should look at first?
