I have a 6032 IR converter tube that I'm building a 20KV power supply
for. I've looked through my catalogs and can't find any caps over 10KV.
I could make a double-ended supply or use a couple of 10KV caps with a
voltage divider to avoid either of them taking too much of the voltage
(you need a divider anyway for the focusing grid) but I'd like to keep it
simple if possible. Does anyone have a source for such caps in the 0.002 uF
range? Also a source for ~100M resistors would be helpful.
Has anyone else out there done stuff like this?

I've looked through my catalogs and can't find any caps over 10KV. These sound like good old fashioned broadcast capacitors to me!!! You could try: Commercial Radio Supply Co (802) 226-7582 Surcom Associates (619) 438-4420 Kintronics (615) ????? (Bristol, TN) and ask for the appropriate Jennings or Sprague mica or vacuum capacitor. 0.002 uF at 20 kV will probably not be unreasonable. Power resistors are another matter entirely... 100 meg at 20 kV (wow!)...try Caddock. I posted this as the mail path was not valid (sigh)... York David Anthony DataSpan, Inc.
