go to electronic goldmine and they have a 35KV rated cap that's .003 uf
golmine-elec.com it's under film/mylar look at the bottom of the web page and go to page 4

ok so should i wire them in series then and will the fact that it will be .006 cause my coil to not work and will those work for my transformer which puts out 15000 AC I dont know if that make a difference or not for caps but thanks for the help

In series they would make 0.0015 uf.
In parallel they would be 0.006 uf.

The Electronic Goldmine capacitor is probably a 302K, meaning that
it is 0.003 uf plus or minus 10%. So it may be anything from 0.0027
to 0.0033 uf. Two of them in parallel will be anything from 0.0054
to 0.0066 uf.

so that should be about perfect then i guess, if it is on the high side would more capacitance the need cause any sort of problems that you know of
THanks
