Original poster: "centauri by way of Terry Fritz <twftesla-at-qwest-dot-net>" <centauri010-at-attbi-dot-com> Hey, I'm about ready to start building my secondary. I chose 26" by 5" for my secondary on a coil powered by a 12kV 60mA nst, but I can't remember why. Do those dimensions appear correct and, if so, how much of that should I actually wind with wire? Thanks.
