I too have run Jefferson Magneteks in this mode, for a couple years
with no failures. My cap was slightly larger than reso at 7nF for a
12/30 nst. I eventually added a safety gap and a LTR cap to be
safer. I used a sync gap at 120 bps and got 42" sparks from the
coil powered by that NST. One just never knows how long an NST
