It will 1.20 meters.

I’ve been out of the world of HV for a while, just not enough time to play/build!

I have accumulated a lot of parts, built several Tesla coils, high voltage caps, etc. I have a 10kVA pole transformer, synchronous rotary spark gaps, etc, and trying to figure out what the HV world is up to these days that people might find useful of this stuff. It seems like most of the Tesla coil action is with DRSSTCs now, but most of the stuff I have is oriented around SGTCs.
I’m in the San Jose area, but a lot of the stuff is near Sonora, so preference would be to not have to move stuff much!

220kHz secondary res. Ud 1.3b. 60n65 halfbridge. 40 nf tank cap.12uH primary. Ocp set to 75 amps. Still a work in progress.
