Hi guys,
I must be missing something here so any help would be appreciated.
Here is a quote from Jensen's white paper FAQ:
http://www.jensencapacitors.com/audio/white-papers/4pole.html
------------------------------------QUOTE---------------------
Frequently asked questions
- I would like to replace the traditional two pole capacitors in my power supply with four pole ones. Is it possible and how?
Yes it is possible and neither so difficult. You should make some minor changes in the circuit where the traditional two pole capacitors should be replaced by the four pole ones.
First of all remove the two pole capacitor and mark the polarity on the panel or circuit board.
When you have a two pole capacitor in the circuit, you have also wires leading to positive and the negative pole of the capacitor. These two wires (or in printed circuit copper band leads) should be cut off near to the original capacitor connection. By this way you get two wires for each pole. One, which leads to the circuit and another which leads to the old two pole capacitors connection point. Simply connect the short wire, leading to the positive terminal of the two pole capacitor to the positive output and the other part of this positive wire leading toward the circuit to the positive input of the four pole capacitor. Make the same on the negative side and your four pole capacitor is connected.
----------------END QUOTE------------------------
Following the text and connection scheme (attached) it seems to me that the "output" of the caps is left connected nowhere. Shouldn't the main rail be split to allow the current to go through the caps???
BTW: I've emailed this question to Jensen's support over a week ago and got no reply so far.
TIA

Explaination
Look on the DNM website for more info on the 4 pole caps. There is a little mumbo/jumbp listed also.
I try to use at least a pair in every DIY product I build now. They can work wonders.
They are much more expensive here, with the dollar/euro exchange rate. The first batch I purchased were 17 -18 dollars each for 10,000 ufd 63 volt. This is double what a corresponding Panasonic 2 pole sells for. Last batch were 30.00 each with shipping.

Has anyone compared the Jensen 4 pole with the BHC T-Network caps? The T-Network caps have the advantage of using slit foils as well.

Hi all,

Thanks Audio Freak, This was my understanding of the way these should be connected but it's not the way neither the text or the scheme of the white paper describes it. If you follow either, the output is connected no where.
I guess they made an error that was overlooked.
just wanted to make sure i wasn't missing anything obvious.
Thanks again,
have a wonderful weekend everybody.

Well actually the text you quoted in the first post describes exactly the image I attached just the language used is clumsy to say the least.
4 pole Jensen's capacitor
I also bought 2 pieces of Jensen's 4 pole capacitors. can anyone here help me understand how to replace original 2 pole one? Should I cut off the wire to positive pole of 2 pole capacitor and connect it to both input positive and negative poles, then cut off the wire to negative pole of 2 pole capacitor and connect it to both output positive and negative poles?
Thanks in advance!

Hi i am also having a problem if i cut in the 4 pole caps as per white paper . then i get a instant short @ my transformer but if i run them (input - / input +) = (output - / output +) the caps hold stable 67.9 volts on both + / - rails, but only using 2 poles off each cap i have tried all the other listed install options but still cant get it my main question here is i have 8 wire transformer 2 main 110 volt with 6 output wires sending 2 voltages .you have 2 poles sending 51.7 volts on each leg taped in center of rectifier bridge thats giving me my 48 + and 48 - rails but i then also have 15 volt poles both carrying 15 on each leg to other locations on board i think for gate voltage control or something i am no pro at this so i could be wrong i just can"t get this to come up without a short unless i hook up like stated (-+-+) HELP

This photo can help:
An externally hosted image should be here but it was not working when we last tested it.
To work optimal, the way its intended, there should be NO connection between cap pins on printboard
The trick of the 4-pole is that power goes in at one end of cap foil, and out at other end
This means that power goes through the cap, instead of just "passing" at the solder pins
ESR/resistance is higher
Multiple paralel caps is less ideal
Aother issue is the foil/pin connection
That always presents a problem
And with 4 poles theres just even more connections to handle
Be aware that there are two different pin versions (Jensen)
And caps are poorly marked, so you need to carefully check the specsheets
I use a single pair of Jensen 15.000uf 4-poles in my 40watt poweramps, with good result
Tho being good caps, I wouldnt use them again
