Over 500V rated electrolytics?

Zap · 16th February 2009, 10:22 PM

I'm helping a friend repair a vintage guitar amp and I noticed that 550V caps are called out on the schematic. Is there a good brand that is available at a supplier like Digi-Key or one of the tube-related houses? Almost if not all the parts I've found seem to top out at 500V.

Thanks!

Sprague still lists an Atom electrolytic rated at 20uf@600VDC. Steve at Angela has them.

Not cheap, but Mouser has these:

600V, 20uF
600V, 10uF
600V, 20uF

Do you have room in the chassis to series connect a pair of 300 volt rated caps? Don't forget the voltage balancing resistor in parallel with each cap.
