Thats cool.  I'll probably do that then.  I only run my coil for a small
amount of time (minute at most).
I'll first measure my current into my NST first and then try some PFC caps
on it to try reduce some current.

Dan,

Yes, most variacs can be pushed to 2X rated current or more for short
periods
according to the manufacturer's spec sheets.

I always ran my 2400 watt, 24" spark tube coil using a 7.5A , 120V variac,
although this was pushing it a bit much perhaps.
