Jensen 4 pole caps

[tinitus]

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
