In Reply to: RE: Eli, would 600 piv be enough for most power supplies... posted by Triode_Kingdom on July 23, 2014 at 21:43:27
wanted to know what the voltage value for the snubber caps should be , .01mfd @ ?wvdc, thanks!

I've only ever used ceramics for this, always rated at least 1KV. Being as Eli is recommending a different type cap, he's probably better qualified to answer your question.

Buy Chinese. Bury freedom.
Ceramics aren't bad and many a part labeled for snubber service contains polypropylene, but Mr. Joppa (a man to heed) provided info. as to why polyester is better.FWIW, I'd like to see something greater than 1000 WVDC parts be used, even in an EL84/6BQ5 amp. However, a 1 KV rated polyester part probably will survive around "12" W. tubes. Remember, metalized film caps. are "self healing".
A quick search did not show any polyester dielectric parts rated above 1 KV. :> ( The "best" solution may be ceramic dielectric caps. in series with carbon comp. resistors.
