And then there is all of the rest of the circuit. Most of the values on the bigger resistors are marginal. It was just painted on the big brown bodies.

Fortunately the replacements are already gathered up in kit form. Just need to get a few minutes so I can fix it all up. Going to go and model the PS, I have some 1k2v SiC diodes from Cree that should do a bit better than the ancient originals. I suspect that the doubler circuit is going to have some big spikes of current delivery. No sense toasting them...
