Yah, it makes HV. This looks like about 19.5 KV. At the moment I'm running it from an Isotap at 110 VAC line voltage.
Had to scrounge for something to defeat the HV interlock. This cap from an old Disneyland pen did the trick!
This chassis seems very stable. I feel like I could be watching a movie tonight if I had a usable CRT. There are other things I can do in the meantime, but none of them half as fun as seeing that first image on the screen.
