Electrolytic cans voltage ratings...

[EFK]

Does ANYONE make "typical" (i.e. JJ, F&T etc.) size cap cans in 32/32 and maybe 50/50 that are rated at more than 500V? Even 550 would ease my mind a bit. I have a few different amps that are really cranking out some voltage and when the power company decides to really cook things at 124/125 AC, some of those initial stage voltages are creeping up to 500-515 and it makes me nervous. And that's WITH a tube rectifier (one of them anyway). Usually I plug a little space heater into the same outlet (don't laugh) and sag the wall voltage down a little bit, but since the electric co.'s here in PA were deregulated this year, that's costing me!

You could always wire two in parallel/series with bleeder resistors across each one. Doing that ensures that each cap only sees 1/2 the total B+

Instead of replacing the caps or usng a space heater, why not make a Vintage Voltage adapter? Vintage Voltage for Old Equipment

Be aware that the voltages on those filter caps are "working voltage" ratings. it is OK to run a 500v cap at 500v. Caps have a surge rating to cover overvoltage.

[olddawg]

Once upon a time you could count on components to be good for at least 20% over the rating. Nowadays, I don't know if I would trust the Chinese reproductions for that anymore. But, I would also absolutely trust Enzo's recomendations.

F&T has numerous cans rated at 550V working/600V surge but AFAICT they are only sold on an OEM basis and rebranded.

Here's an example from a German distrib:

Series stack is usually the best way. Parts should last longer too not be'n run right on the edge.

I've used two caps in series for the first filter off the rectifier for the voltage safety margin. Weber also sells some 600V e-caps, and reasonably priced.
