i don't think the power supply was running. according to the vids i watched, there is a standby power supply, so the remote will function, that runs diagnostics before returning a signal to power up the main transformer. i wished i had cleared the protection history, and then tried to fire it up. i may have worked. but why did the protection history show current issues initially?
the only multimeter tests i ran before tearing it apart were nonpowered tests, while still in the circuit.
i have all the power transistors out and have tested them with multimeter. tests done with diode function. they are pairs of sk a1695 and c4468 transistors, 7 pairs. all the results seem consistent. no continuity between collector and emitter. base to emitter and base to collector readings are .31 to .5.
there is continuity between collector and the plate where the mounting screw goes thru. is that normal? and they still all test as diodes on that component tester.?
one thing i forgot to mention. when i did the diagnostics, it ran "manual test, all". i had speakers and headphones connected and i got white noise thru the headphones. the unit has a internal signal generator.
thanks for your time.
