I’m changing the capacitors on my receiver and I found two big capacitors on the power amplifier board. They both have four pins and when I look at the back of the board I found that oly one looks like a dummy. Hi Can’t find Anything the Web that looks like that. Somme People talk about 3 pincapacitor that are in fact two capacitors in one with a common negative pin. Is there someone familiar with that kind of capacitor that could help me?

As both label, schematic an PCB layout show, you have a single 2200uF x 35V capacitor.
4 pins?
One of them is positive, other 3 are negative and most probably connected to aluminum case (they *might* float though).
Check for continuity between them.
Why 4?
For mounting and stability.

Probably not helpful but:
Nippon Chemi-Con Corporation / Aluminum Electrolytic Capacitors
The site says replacement series for EW typ is SME.
but it lists it as a :"SCREW-MOUNT TERMINAL REPLACEMENTS"
Then it lists the SME as a "SNAP-IN REPLACEMENTS" and the replacements are SMH / SMM series...Which do not have the same 4 pin pattern as yours.

Thanks to everyone! It was more obvious what it was once remove from the board. Here are some picture of the work done.
