Leaky capacitors need replacement?

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.

These parts are being used in the DC Blocker inside the amp.

They should be replaced with the same value and voltage. @timlub has mentioned some nice quality parts to replace yours, which have a tendency to do this long before their time.
