[Amps] Russian HV Supply Capacitors

[Carl]

Those new caps are fine and on a par with the CDE 381LX series.

The improved 381LR is the current standard of comparison for ripple current 
ability. Cost is lower too.

The only way to completely test caps is in a PS running at its intended 
voltage and current.  You can do an approximation with a 0-450V bench supply 
and what ever resistive load it can take safely and monitor case temperature 
and current thru the cap AND at the load.
