4 pole elecrolytic capacitors

[pmkap]

Although my needs and fiscal constraints probably preclude their use, I was wondering if anyone has actually used 4 pole 'inductance cancelling' electrolytics in their power supplies.

Black Gate suggests the use of their non-polarized N series electrolytics in a back to back arrangement that essentially emulates the 4 pole configuration. One can see this in the Michael Percy catolog (a pdf file) at the bottom of the Black Gate entry -

Jensen is making their tissue paper aluminum electrolytics in a 4 pole configuration. (though I wonder how much of the benefits are attributatable to their lack of plastic sleeving) -

BHC/Aereovox is offering slit-foil, 4 pole electrolytics in their new ALN series (bottom of the page on the url) -

Thanks in advance,

I have, BGs and Soshins. They seem to work. At present I am running an ADC at 24/96 with BG Ns 4.7 uf coupling caps. It beats the use of a single BG.

Let me know the result if you go ahead.
