I didn't realize the Leslie amps were like that either, but then I looked up the schematics as a result of this thread. Sadly, both of mine are solid state. Anyway, the series VR is acting like a Zener, not as a forward biased diode. The B+ would have to sag a lot to create the effect you're describing, enough to extinguish the tube.
