Original poster: "Nele" <morfeus@xxxxxxxx> Hello All: Does enyone uses "EPCOS" polypropilene capacitors in Tesla coils? I have over 100 of them, but don`t know if anyone has any experience with this type of caps. Anyway, I will try them, but just wanted to know if they are of good or bad sort for this purpose... before they blow up... Regards, Nele
