I have a Drake L-7 linear that has blown the "printed circuit board"
capacitor C-41 that is across part of the RF choke RFC 4. This choke
sees the total amps drawn by the linear as it is in series with the HV
input from the P/S and feeds the two 3-500 tubes. However, I don't
know what voltage rating a commercial part would be for a replacement,
and if it could be obtained. Someone has recommended at least a 5KV
rating.

Anyone have any ideas on a replacement??? Also maybe I could make one
from some double sided glass PC board I have here. The cap in the
linear is 1 inch by 3 inches in size. There is also another one of the
same type, but much larger hanging off the "load" variable capacitor.
It seems to be in good condition.

I have found nothing else in the linear that looks bad or measures bad.

So it looks like the C41 cap failed and took out the 0.82 ohm resistor
in the P/S HV lead. At least I hope that is all that is wrong.
Appreciate any thoughts anyone might have on this subject.
