I think if you were you introduce enough magnetic force to distort the rods in one of these valves it would be a phenomenal EMP, and burst the envelope
I'm quite sure if there was enough sensitivity, as Trevor said with the 1j42a, then an alternating audio signal with a net magnetising effect of zero wouldn't cause a problem.
It's interesting, but my curiosity doesn't extend to operating them while detonating a small yield nuclear weapon in the potting shed
Hi Amie,
I thought my mention of the EMP may have been a bit too far, but was really just a passing thought as I am not really conversant with the physics of them. I take your point about the AC field.
My thinking on the 'warping' of things was perhaps more with some of these really powerful mini magnets that can be obtained these days. I would think that any small magnetic structure would be affected and, with their small working dimensions, a very small flexion, permanent or otherwise, may cause what you have found. It does make me wonder whether the field is affecting the electron beam or the structure hence the beam indirectly? Perhaps an electrostatic field (compare oscilloscope CRT with scan plates and TV with scan coils)? Maybe I go too far again although this discussion is giving me one or two thoughts
