Re: cere-mite caps

I bought a lot of 10 ceramite doorknobs about 5 years ago that are 4000pf and 40,000 volt, so 2 of them in parallel would work on a 15/30. Performance was not spectacular, but they did get amazingly hot after very short run times. The same capacitors worked quite well in Dan's Marx generator. I say to stick with poly foil film capacitors. I have had very good performance with that style of capacitor, even if they were not CD 942c series.

Before planning on using those I'd sure attempt to find out what their
dissipation factor is; they could be "high k" bypass capacitors and not
particularly useful for high frequency work.  Probably do a Google on
the part number and the manufacturer's name.
