I am rebuilding a Heathkit Ho-10 and I'm looking for the high voltage
filter caps. They originals were 0.15 mfd at 1600 volts.
If the transformer really puts out 1200 VAC then I believe the caps
should have been rated at 2KV. I can not find any rated at 0.15 at 1600
or higher voltage. Does any one know of a source.

Were these originally paper or oil caps?

Putting lower voltage rated caps in series to achieve the required cap.
worries me because the adding voltage equalization resistors across the
caps would increase the current pulled from the marginally rated power
transformer.

I think that Electronic Concepts in NJ still makes film capacitors with
voltage ratings this high, but they won't be cheap. And .15 is a little
bit too high for a ceramic (and you can get plenty of ceramics at that
voltage).
