Looking for hard to find replacement caps

[Justintime]

Hi everyone. I’m new here and this is my first post other than introducing myself. I’m having problems with an amp of mine and have decided to replace the 4 big caps. My amps is a PS Audio 200c and the caps are Mallory 15000uf 75vdc. I don’t have room for any longer than about 80mm by 68mm but could go narrower. The number on the Mallory cap is
CGS153U75W3C3PH

I’m looking for a screw cap that will be as close of a replacement as I can get that will fit. I know very little about this so I’m hoping I have given enough info and that someone might feel like helping me. Thanks in advance

What kind of problems? It may not be those caps.

I’m getting some slight hiss and static through the left channel. I have noticed lately that when I shut the amp off, I don’t get the whooosh sound of the current dumping from that channel like I do the other side.

I would get it bench tested, those symptoms don't point to the main caps being bad.
And those are the most expensive parts in the amp.

Ok. I’m going to do that first anyways but figured I would change those main caps anyways. I had all the small ones changed a couple months ago

How old are the caps? How many hours have they been used?

The form factor will be difficult to replace. Check with PS Audio first, in case they have back stock.
