Hi i found my PA0016 output pins all value are -16VDC, it means broken or any others, would you advise me, thank you.
That should definitely be broken.
Just be sure to check everything else before powering up the amp with a new IC.

Did you ever fix yours? Have a m90a myself with same issue ( i think the pa0016 chip)
PA0016 substitute
By the way I designed a tiny PCB substituting the chip.
Have not tested it though.
I could provide one for tests at some point.

Can someone with schematics for the ML333 forward me a copy, jlithen or m levinson? my tech says that the output boards or something had been damaged and questionable restoration had been done to them, and he doesn't want to fix it saying it would still fail after sometim. Can you send me a copy of the schematic? Not sure how you can do that as I can't find any way to pm you and you can't provide email address in forum thread
tech says only way to ever use them is to completely rebuild the boards. the 333 turned on will trip the mains circuit breaker at home
