I wouldn't worry about the difference cost wise between 30A and 60A draw.
Assuming you run it for an hour a day at ~14 kW (plenty enough to
annoy/scare the neighbors/police/swat team) over a month that's $84 vs.
$42 for ~7kW. I seriously doubt you'll actually run it that much before
spark gaps need replaced, ears need a rest, etc. I think it's always
easier to use inductive ballasting and cheaper. With caps you'd need lots
of them in parallel to handle the 30-60A and you'd need lots of uF (about
100uF for around 25A limiting off the top of my head). I haven't actually
tried this myself, but seems like the caps would heat up like resistive
ballasting. I personnly would just use the hardware store ballast, (2)
500' rolls of 10-12 awg for 26A limiting.
I just got my new bigger variac, it is a new dual 120V/22A (motorized)
unit that I paid dearly for, and I really do not want to burn it out, what
should I do to get the current down to 22A@240v? Again this was for a 6 or
8 mot stack (which is just until I can save up for a pig or more neons as
all I have is a 6kv/30ma neon (and that is just not enough for my 4 inch
coil ;-)
Thanks Again
