Default Tube PWM driver

Yeah, so I got bored. Here's a five tube PWM generator circuit!

Depending on the output level, it should be basically ready to slap onto an SE output stage, actually. Just add a plate filter choke so the switching noise has somewhere to go.

I have no idea if the hysteresis resistors are enough, if I ever breadboard this I guess I'll find out.
