Hi Phil, I had this prob before, You may also want to insure R661 did not
increase in value. Should be 470 ohms. It monitors the B+ for regulation
feedback.

Originally dead, Q602,Q602, the VDRs, .1 ohm resistor replaced. Plug in,
instant short again.
Final fix was a 150 volt zener that checked good at first: D648 (150V
zener) across the +130V source to ground.
