We are upgrading a Hafler JF2000 Signature Series power amp with new caps in the power supply.
Have any of you experimented with caps from Rubycon, Panasonic (Matsushita) or Nichicon? Research on the net tells me that the Rubycons are the best.
What's your experience/opinion?

Is this the inside of half of your amp?
The question is what can you get that fits. you're looking for 42,000uf+  80VDC rating. (originally Sangamo DCM)  Measure and see what diameter and length you can accommodate, as that is going to be your primary constraint. Let us know what they are. Then you will be able to select from the available industrial, screw terminal, large can electrolytics.
The small electrolytics on the board could also probably stand updating, along with the rectifiers, and put snubber(s) on the secondary(s), etc...

FWIW,
Paul

All those brands are good. Haven't had a problem with any of them. Look for 105 Deg. C caps for a better quality unit. Low profile caps are available too. You might have to parallel caps to get what you want, or do that to improve the amount of filtration.

Yes, that is the bottom half of the amp. This particular example was built by the Sound Valves company (same people who built the Dynaco series 2 models for Panor Corp.).
As luck would have it, I located one the techs employed by
John Peterson / Sound Valves who now lives here in the Dallas/Ft. Worth area. Mick was there from '95 thru '01. He worked on these amps as well as the stuff for Dynaco, and the original Sound Valves tube designs. The amp is now in his hands for the upgrades. He does a lot of guitar amp work as well as audiophile related projects. Small world, huh?
Thanks for all of your help on this!!!!!!!!
BTW, this amp built by Sound Valves, was known as the Mosfet 32 (16 output devices per channel).
