I wound up with another 530S and am giving it a going over with these procedures. So far so good.
Wanted to make a note that I got bit with the plate voltage that goes to the driver tube when I touched
the rear bandswitch wafer. Turns out on the rectifier board, R9 (330K) was completely open, its the bleeder
resistor for that supply and its a common fail in many of these, so if you are going into this board, check or replace.
Also the (2) 56K half watt resistors on the board forming a voltage divider also drift pretty far out of tolerance and
ought to be replaced.
