Hi All,

Last month, after 30+ years of flawless service, my pioneer sx 450 started to have a constant 50Hz buzz through the speakers. The music from radio or another input can still be heard fine at the same time.
I opened the old machine up, and couldn't find anything obvious except for some dust that I took away. No loose wires or loose components.

Does anyone have an idea what this could be?

Thanks,
