I did say"usually"! to cover my butt.
I can't account for this distortion either but I have seen loads of badly made valves with bent pinches and always assumed that it was poor manufacture, possibly post assembly annealing.
Can anyone prove us wrong?
I have seen power valves and rectifiers that have become plastic due to excessive heat and distorted that way.
