350v and I think the cathode resistor is the cruddy one in the better angle view chassis pic. It's hard to read as it old and flaking I did not change it because i'm not sure of it. looks like green yellow brown making it 540ohms the other one i did change in that circuit i did replace with a new one and its 510k it hooks in with one end of a 50v electrolytic with neg end joined with the cruddy( cathode resistor?) and the new 510k.

gahhhhh! my heads turning into spaghetti wiring
