Did you do the aforementioned thing with mains AC power?

Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.
My computer doubles as a space heater.

Actually I do not gain any enjoyment from such acts, so no - likewise I have never connected a capacitor backwards and let it explode either. Accidental, yes, but fortunately never let it run enough to cause rapid uncontrolled expansion of even fuhjyyus.Comment

Re: bent neck CRT pins...
i have seen worse looking getters on tubes that showed fine.
hook it back up without the shield and look for arcing .
or apply 6.3v to the heater and see if it burns out in a few minutes.Last edited by kc8adu; 04-17-2016, 06:18 PM.Comment

Re: bent neck CRT pins...
Even with white stuff on the getter deposits? It's clear. I think all the observations made all point to seal breach. First starting with focus destruction(the electrons hitting air particles makes good sense.)
I can't really test for arcing because the PSU shuts down immediately (and burns fuse) with it hooked up to the CRT. PSU powers up fine only when the CRT is not connected - there's definitely some higher than expected current path through the CRT though an ohmmeter cannot detect (air).
The heater is slowly becoming more resistive over time. This is a clear sign it's burning up, there's no other good explanation other than seal breach.
Thanks for trying to give some hope...though I think there is none left, not to mention I think I actually see glass cracks
