Yes, EVR, he'll have vacuum-tube rectifiers, vacuum tube transformers, a vacuum tube camera to capture the results with, and he'll just upload the pics to the site with his vacuum tube PC and vacuum tube internet.

Of course, I do not even plan to use a diode for the doubler on the MOT. As I mentioned earlier, I was planning to do it without the doubler and run the VTTC on AC power. If the time comes where I might need a doubler, I can always try my 1616 rectifier.
I think I may have a tube that could work for experimentation, a 4-400A. The driving power is under 10 watts, so a TV output tube could be used to switch the grid feedback easily. The 4-400A is a tetrode, so I could also try the idea of pulling down the grid to ground to shut off the tube, but this method may lead to arc-overs, which worries me a bit.
Below is a schematic of the preliminary idea. Also thought about maybe adding a time delay relay (yes, a tube-based one of course) in series with the MOT to allow the rest of the circuits to warm up before the HV is activated.
