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.

I agree with Bill. The Soviet caps are very heavy duty and
conservatively rated. I use a 50 uF/5kV version that looks identical
and like it very much. I also agree that this one is overpriced, and
the shipping is outrageous.

Two comments:
1. I have never used those personally, but I am a big fan of Russian
stuff.
Built very conservatively and tough as a tank.
2. Those particular items are WAY overpriced. I'd do it with a string of
electrolytics.
