Music Angel XD950MKII capacitor issue

[Elfox]

Hey all, I currently have a working Music Angel XD950MKII, but that is only after replacing some of the capacitors in the driver section, as it smoked in just a few minutes after the initial startup. Guess China-made 450WV capacitors don't necessarily mean they can actuall work at 450WV! Anyway, I have another capacitor that is starting to bulge, and I would like to replace it. Problem is, I can't identify what the value is. Have any of you come across this problem, and/or doesn anyone happen to know what the value of this capacitor is? There are two, one for each channel, but the ones in mine aren't the same and aren't marked with anything meaningful. The one that is bulging is the one on the right, this picture was taken prior to 'the bulge'. Thanks in advance! ~Elfox

You'll probably get a better response if you could post a pix of the writing on the capacitors. But generally, it's hard to have too large a value for bypass caps that will fit in that physical space and have that lead spacing. So an alternative plan is to see what Panasonic or Nichicon or other quality cap with 450 VDC or better rating fits, and declare victory.


YOS,
Chris

Thanks. I'm going to try and get some better pics tomorrow of the outside of the capacitors. The last pic was a snapshot of a video I made when unboxing the amp. I was just hoping someone had come across this before and knew what the values were.

Schematics please ! Changing components after their look is less then perfect.

So disassembled the amp today and took some pictures. These are the only markings on the exterior of the bulging capacitor, which read "2(2)" and "2I". There are two that appear to be placement mirrors of each other on the circuit board. The other one is the second picture, and it has different markings "65". If no one knows what these values are, I will probably take them out and measure them on a capacitance meter at work. Doubt the bulging one is still the same value as it was from the factory though... 🙁 If anyone has any idea what the values of these capacitors is, PLEASE let me know. Thanks in advance
