Pioneer SX-950 missing voltage in AWH-050

[goblin11372]

Hello
I'm trying to repair SX-950, replaced all the caps and the transistors which were recommended in this forum but I still have one issue-
Maybe it's lack of my knowledge (doing this kind of repair for the first time). I followed the diagram of power amplifier assembly for AWH-050 when checking the voltage and it looks like it's missing -49.5V on pin 15 and 30. I'm checking with the meter, attached - to the chassis and + to the pin- (15 or 30)-am I doing it correctly?
Thank you in advance for any suggestions

Found this equipment in the dumpster at my work, it had extensive damage on the power supply AWR-101 and AWH-050-see attachment

That -49V comes directly from the big PS caps, so if it's missing that would seem to indicate a busted wire or some dead rectifiers.

Check the voltage at the big caps.

Thanks a lot for the help, you were correct, one of the wires was broken next to big capacitors

Thanks again!
