I suggest you look at:
www.electrojumble.org/reforming.htm
I have used a variation of the circuit found at:
http://www.vmarsmanuals.co.uk/newsle...s/big_bang.pdf, or search "capacitor reforming-or how to avoid the big bang". I incorporated a 0-1ma meter, activated through a momentary spdt switch when neon lamp goes out ----shows leakage less than 1ma. Combined, these sites should give you some good info.
