Go with the WIMA DC Links, not VISHAYS.
Readily available.

WIMA DC-LINK MKP4 or 5 or 6? Or what?
Observe, before you think. Think before you open your yap. Act on the basis of experience.
Hi Jeff,You've been giving us some good advice. I appreciate it. How many men can get PJ to amend his circuit?
I found at Mouser:
WIMA
50uf 600v $25
50uf 800v $25
100uf 600v $43
100uf 800v $45You get ten 100uf 600v for $395. Call it $400.
$43 is a boutique cap price. Clarity Cap same value, and maybe $7 bucks more, or maybe the CC isn't such a boutique price after all.
I've liked WIMAs for a long time, but I've only heard them as coupling caps. I always thought they would excell in the PS. They are perfectly good coupling caps, and what more can you say? I have a bag of .22uf 600v ones.
Would you use them in C1 position instead of a good PIO or Film in Oil? I think I would like to use the wima in the ultrapath position.

Big speakers and little amps blew my mind!

Panasonics run about $15 for DC link.
No audio experience here, just a Scots connection ...
Panasonic DC Link at Mouser
100uf 500v 4 pin $21
Ten for $200. That's half the price of the WIMAs. Not too shabby.
Do all 4 pins have to be connected?

Here are some Scotch caps for ya.
Russian electrolytic 100uf 350v caps. 10 for $15.
Are the connectors a pain?
Big speakers and little amps blew my mind!
Just build an isolated bracket for mounting unless you use your chassis as ground which is an art to itself..it would be cool to hear them...
Stuben
Good point.
If the connectors work in your application they are fine. I would try and find out when they were made though as they are electrolytic.
Although if you are trying to achieve a specific grounding scheme, these may limit you as they will be grounded to the chassis at their particular locations.
Aside from that, what's not to like, simple and easy installation and only one wire to connect.
The safest suggestion I have already made, was to use WIMAs, as they HAVE been sonically evaluated and determined to be superb !!
Cheaper DC LINK stuff, have NOT yet been sonically evaluated, and so, those cheaper ones may be more expensive !! :-)
I use the higher VDC rated caps, 800 or 900 VDC as I recall, and use in the C1 position ... it is fine !!

My last name is Scottish, and I save my money.
Thanks for the great tip PJ!
