Well, I hooked it up to 2 Mots in series, for about 4800 VAC. Current was
intense, I figured 20 kv at 8 ma for 160 watts. At first I though I had
killed my diodes after about 30 seconds of running because it stopped
jumping the gap, but the arcs had been blastign away at the
electrodes(evident in the red sparks flying off) and causing corona
production to get worse and worse and thus stopping it from reaching a high
voltage any longer. Corona is quite powerful, if I place my hand near the
high voltage it feels like a 5 mph wind is hitting me. I am limiting current
on the output through a 100K 1% resistor that seems to have acquired a
resistance higher than 2000M(note: throwaway Beckman multimeter). Found some
small neon transformers for charging it, should I go with the 4000 VAC or
5000 VAC one?
