Default xtant help

well once again i need some expert help with my xtant. i ran into some financial problems lately and can no longer afford to send out my amp at this moment to be repaired. When i first started my thread for someone to fix it i said it was the fosfets, which are burnt, but i also noticed this after reading up on busted amps.

The pink x's on the picture mark the doohickeys, and they are all buldged outwards. i had the amp next to my working ones and noticed it finally.

1) what are they called?
2) how hard are they to replace?
3) where do i buy them?

im gonna try to repair the amp myself to save some money. if i mess it up more...well it doesnt work anyway. the top two on the left in the picture are bubbled out more than the two underneath them. and the 3 on the right are also bubbled upwards. any help would be greatly appreciated. thanks guys.

the ones on the right specs are
35 V
8200uF
0104 (M)

the ones on the left
250V
330 uF
1273 (M)

the ones in the middle lay flat. i dont see anything wrong with them from the outside, they arent buldged up or anything. thanks everyone.

They are Capacitors. They are not cheap but they should be replaced.


People have disputed the wikipedia page about it but the explanation seems solid to me.

Capacitor Hydrogen venting aka capacitor plague
