How do you determine the  amout of amps drawn during operation?
I have been using 12000v 30ma neons that are rated at 3.6 amps each
I realize they are inefficient transformers but
putting 2 in parallel for 12000v 60ma I have had no problems
pulling through a 12 amp variac...

I have recently decided to up my PS to 12000v 90ma
but am unsure weather I will have to use
a PFC motor run cap setup to pull through my 12 amp variac
