I have a SA-HE200 after overload kicked couple times now no sound from speakers but it powers up. What's the fix?

Most of the newer amps have internal fuses for people like you who like the volume a little too high.
Do you have enough troubleshooting skill to open the chassis (UNPLUG IT FROM THE WALL SOCKET), and look for
any internal blown (speaker) fuses?

Sir Dannycobb1 . . . . .

With all of those years passage . . .likely the liquid portions aspect of the POWER AMPS heat sink compound has creeped and transmigrated lateraly and now is leaving the heatsink with a thermally insulative barrier of only its tin oxide element .

Fire it up through a lamp limiter so that voltages and currents can be measured without blowing fuses.
