Hi folks. I just picked up a non-working Sansui AU-7900. It has no output on either channel, either through the whole amp or directly through the main in jacks. I measured about .5 VDC on one channel and like .005v on the other. It did come out of protection fine. I opened it up and saw nothing obviously bad, but the 1A fuse underneath was blown, though not badly smoked. When I replaced it and powered it up on a dim-bulb tester, it lit the bulb and would not come out of protection. All four of the 220 ohm fuse resistors on the power supply board measure way over 220 ohms in-circuit--I'm getting like 2.2 meg ohms on two of them, 330k, and open line. I read through this thread here. After I replace the fuse resistors and replace the little glass bead diodes with a pair of 4148N in series, is there anything else obvious that I should do first? I don't have a scope but I have a multimeter. I am planning to recap/re-transistor the boards but obviously I wanted to get it working before I did that.
