Seems like that unlike a tube, the output transistor is a 'hard switch', capable of driving the "fly-back" spike ((from which the HV is derived) to far higher levels than a tube could possibly manage. |
So the "HOT redplating" I've heard of could be caused by a regulator failure? Better to blow *a* tube than *the* tube.
