Original poster: "Andy Cobaugh by way of Terry Fritz <twftesla-at-qwest-dot-net>" <kb3ewy-at-rcn-dot-com> I am considering bidding for 3 BYCAP caps, 0.02 uF 10KVDC. My question is what dielectric is in these caps and/or would they be advisable to use with a 12/30 NST? I would use them in series to get the exact value needed for resonance with the NST.
