A good plan is to stick to a 3x rating. All the caps that I use in TC
service are now rated for around 40kV, ever since my 25kV MMC went up
firecracker style. Too many volts, and that was from a 10kV neon, with
safety gaps!!!

The theoretical peak output of the NST is 6500V x 1.41 = 9165V. I reckon you
should build your MMC to 20kV, that way it is very unlikely you'll kill it.
