Original poster: "Bart McGuyer by way of Terry Fritz <twftesla-at-qwest-dot-net>" <bmcguyer-at-houston.rr-dot-com> Hey, I have a few 15Kv doorknob caps that I want to use for misc. stuff (Marx, etc...) and I was wondering how much I could possibly over-volt these guys? Also, any suggestions on how to rectify the output of a neon for real cheap? thnx, bart mc.
