Updated this thread with the first post's addition of the most simple possible demo fusor power supply diagram as well as a much more involved and complex hookup for those who might want to be in the plasma club with metering and filtering added and current limiting for a final supply that can even do fusion in future.

The more complex the idea put forward by the poor amateur, the more likely it will never see embodiment

I recently lost a HV diode in my bridge circuit (second time. Getting old. Haven't bothered to fix it with so much going on.)

Having a Neon Sign Transformer (NST) makes determining the bad diode rather simple. Just hook up one side of the NST output to my fusor input HV cable, and measure the diodes in the bridge.

So besides use as a demo power supply, a NST is extremely useful for testing very HV diodes (20 kV.) With a variac, could be used for lower voltage (1 kV and up) diodes, as well.
