I'll run it low, i'm not feeling to ambitious with my new mmc. I'm going to take all the precautions with it and make a safety gap for my nst etc. (off topic, but not important enough to start another thread) If i'm using a variac to control the nst should my safety gap be the distance of the arc at full power? (i'm guessing so)

I just tested a 1/4W 10M resistor here.
At 4200VDC it arced over on the outside. Seemed fairly happy at 3000V... So at 2000V peak you should be fine. Seemed the heating at around 3000+V was the biggest problem.
Cheers,
Terry
woh, are these actual high voltage rated resistors, or just any old standard resistor? Only reason I ask is I have an almost complete spark gap coil sitting here (super secret project!) but no resistors across the MMC caps. My local stores are out of the HV rated ones, so I daren't fire the thing up just yet in case I kill the MMC
