Leaky capacitors need replacement?

If you are ordering caps, you might as well order and replace all the electrolytic while you are at it. Also there is never a problem with getting higher voltage or higher temperature caps, in fact it is recommended. Just check the size. You’ll be quite surprised with how much better it’ll sound when you are finished;.

Are you saying to replace the electrolytics with new electrolytics or use something else?  These are right off the AC mains between the IEC plug and the rest of the amp. 

Are the one's in the picture electrolytic or something else?

Electrolytic.
Minus - sign on black strip down one side of the cap, donating which leg is minus.

Absolutely.

On the electrolytic on the boards, I would recommend Panasonic FM, Nichicon KZ or FG or Elna Silmic II.  These caps all perform at a very high level.
