I agree with Carl here. I had a string of 220mFd 500 volt electrolytics meant
for photoflash work: even in a choke input filter, they didn't last very long
before squirting stuff out of the vent holes. The Sprague 36D computer grade
electrolytics I replaced them with lasted for years, and have only been taken
out of service because there's an Acom 1500 due to arrive on Monday!
Capacitors meant for SCR commutation are another matter - they are designed for
continuous high currents

Subject: Re: [Amps] Russian HV Supply Capacitors
I still wouldnt use any laser discharge caps in an amp PS; they are pulse
rated and do not handle current very well. There have been numerous reports
of US caps going back to the 80's that literally exploded when run at full
voltage. Derated to about 50% they were OK at least in a 1200W amp PS.
