Dan -

That would be impossible with a standard NST and continuous load. What was
the duty cycle of your load? What did you calculate for an average wattage?

I have a franceformer 15kV/60mA transformer.  With a high voltage adjustable
electronic load we have a work, I've gotten about 65mA at 15kV before the
NST current limits.
