Default 4 pole electrolytic capacitors

I have a question for the more theoretically strong persons here.

Would it be a good idea to replace the C1-C4 and L1-L2 in the SOZ powersupply with two 4-pole electrolytic capacitors, why? why not?

It's explained in this link:

http://www.jensencapacitors.com/audi...ctrolytic.html

It sure look like the perfect substitute ..

(note: You need to scroll down a bit)

Also check the white paper, here:

Four pole electrolytic capacitor - Four terminal electrolytics with superior high frequency transfer impedance and transient and noise attenuation/suppression capability. As the input and output circuits of the capacitor are decoupled from each other by means of an inherent filter formed inside the capacitor winding, transients and noises coming from the mains cannot pass through the capacitor and reach the primary signal path. The four pole electrolytic is the ultimate reservoir capacitor choice for switched mode and traditional power supplies.
The inputs and output are not decoupled from each other are they? don't they have direct connection with each other via the plates.

However it is a good idea to get the power running right the caps, but i think this has been done for AGES it's just that most people connect the two terminals together on the OUTSDIE of the cap too (and maybe deleteing any advantage). But if the foils are thin (which they are) would you want ALL the current flowing though it on a big pwer supply?

Food for thought, hmmmmm

Not accordoing to the white paper.

If you connect the inputs to the outputs, you just end up with a normal capacitor. If it is a normal capacitor you want, it is much cheaper to buy one those.

Well, the ones I was looking at were the axial type especially the 8200 uF 63 volt version, which has a rated pure AC load of 9,9 A @ 100 Hz, which is more than enough for a 25 watt SOZ, which demands about a third of that.

Default T network capacitors

This reminds me of the work done by Denis Morecroft of DNM in the UK on 'T network' capacitors.

http://www.dnm.co.uk/

These are manufactured in the UK by BHC Aerovox.

Did anyone actually try building the SoZ with these four pole capacitors? If so, we'd all love to hear what the results were.

Also, are there high voltage (250V+) versions available?
