Hi all,
Several years ago now I built a giant musical tesla coil, but never told any of y'all about it.
Figured it's worth sharing
- Bridge caps store 1.2kJ with 120mOhm ESR - Tank is an MMC from the foil plate CDE caps everyone loves - Coil diameter, 14 inch. Built on custom formed fiberglass tube. - H bridge is 2x CM1400DU-24NF, with isolated 20A gate drivers. ~300ns rise time, beats the datasheet by a factor of 4 - Peak current limited to 1500A - Bus voltage 350V or optionally 590V on 208V. - Polyphonic midi control
It took about a month to built. Been going strong ever since, even surviving multiple rainstorms.

It is pretty clear that you are running without a single break out point, but do you have multiply small break out points or is it just the toroid having a real uneven surface?
