But film it because if it goes it goes very well.
As in "Y'all hold mah beer and watch this now"? ;)

What does shorting the power transistors actually do in this case? I always thought it was usually considered a Bad Idea.

You're bridging the cathode to ground. Beam current will go to the maximum the tube is capable of. This will try to produce soft X rays but a pick off from the HV transformer will monitor current and shut it down. There are several other redundant safeties.

But...
If you see something like this I'd probably have to have a schematic to figure out how to do it right.
