I got my 811a induction heater working, I think its a very cool project also works like a VTTC. I also have two 812A tubes too. I have a future for them.
I'll post some pictures soon, It looks a little slopy right now.

Is that big tall green thing in your picture a grid resistor? If so that explains abit. Also are you useing another transformer to limit currnt and to get the full voltage from the wall?
