Ok, I got it No heat from anything, but I'm not sure the 1N004 protection
diodes are working, I get a zap with my fingers across the backs of both of them.

It's hard to see with the video, but they are two channel software PWM,
the light is moving back and forth between the two neons.

I think the transformer primary in the original circuit was very low impedance.
It's a short on my continuity meter, it's so low. That would look bad for the MJE3055 output.

Still have to sort out this stray high voltage problem.
