Snap-in leads, at least in the Muses, are magnetic.

Many thanks and good luck.
Nichicon KG's have been highly recommended to me. I'm yet to take the plunge and get them though, I need 80V+ so somewhat more expensive!!! Percy Audio stocks them. Though in those values (15,000 and 22,000) he only has 50V minimum. not cheap but certainly seem to be a lot cheaper than the "computer grade" Rifa's or Aerovox caps that I have looked at as alternatives.

I can tell you that I have had some bad luck with a brand called Samawah. The application I am sure had something to do with it, but the failure was spectacular and burned the solder lugs right off a 15,000uF cap not to mention burned a hole clean through the circuit board. Made one hell of a stink to when it let the smoke out as you already know.

Samwha makes reasonably good caps but I would not use them in fine audio stuff considering the availability of better caps like Pana FC etc.

When applied wrongly (i.e. polarized in reverse ) even the best cap will blow in a spectacular way.

These were OEM stuff(I won't mention the manufacturer, so don't even ask) and not enough over rating to allow for any tolerance. 50V rated caps in a supply that ran at 45 Volts. So I guessI shouldn't blame the Samawahs.

They weren't installed backwards(or in other words reversed polarity) but putting them in there in the first place seems backwards.

You are so right too many other good choices available.

rianco, te rif'a are about the best power supply cap out there, costly, but exceptional life, low esr and everything else you could want. I'd rate them above the Keindels and Nichicon/Rubycons PS caps. I use the Mundorf PS caps in a pre-amp supply, they are good cap for the application but for a power amp power supply I'd go with the Rifa's.

The BHC's are also good, try Audiocap.net, uk based...

I've read that others have had this problem as well... One person went to the extreme of sending some money via paypal (or mailed a cheque can't remember) to show he was interested, apparently got a quick response... I haven't yet tried, from what I have read your experience is pretty common, and faxing instead of emailing might be more likely to get a response.

Apparently the other thing is if the query is anything other than an order enquiry he doesn't answer. perhaps try putting order details in the subject eg want to purchase 10 XYZ caps ....

Tony.
