Dude, R804 has got to go. It's clearly gone sour and is probably bringing a supply line or component up too high.
Here's my replacement parts list for the important PSU resistors:

I also have cap lists. I'll share them later, although I could not find a replacement for the one bipolar 3.3µF @ 160v cap that lives in the H circuit. They just don't make bipolar caps with that kind of voltage tolerance anymore.
