Are you placing the power factor correction caps in series? When they're in 
parrallel, like they're supposed to be, the NST can't tell the difference 
(except for a few extra volts because of the drop in the line voltage). I 
was thinking about putting some PFC capacitors in series, to resonate with 
the NST and cause shunt saturation, but I wont touch it untill I finish my 
DRSSTC.

I think I found my problem. My Power factor correction cap's were of
sufficient value (150ufd) to run two 15KV/30mA NST's. I was down to one NST
when I was trying to overcome other problems.
I believe the leading power factor was to blame. I now have two NST's and
they will run for 5- 10 minutes before showing signs of getting warm.
I am excited about my new coil.
If I have time I will post some photos. :-)
