That dark stuff could be some kind of glue they used to fasten the elco's to the print. Do the other elco's also have this black stuff at their base?
I would be more concerned about that transistor-thingy next to the elco. It seems like this one is getting pretty hot. It also seems like the package is split in 2

The only glue in evidence is clear stuff on the main PS caps elsewhere in the amp. This stuff seems to have oozed down due to gravity (its mounted vertically). Ive been worried about the what i assume is a regulator as it seems to have slightly browned the casing of the cap next to it. However i think its meant to look like that with regards to splitting in 2 as it seems to uniform.

Fuse replaced and amp working i both channels now for 30 mins with no problems. However there seems to be a small amount of heat coming from what i believe to be the regulator mentioned above (although i guess it could be soemthing else).

Not sure if this is normal or not? (its not in the power amp section so my guess is not)

That glue is not the nicest stuff they could come up with to stick the elco's but I wouldn't be too concerned about it.
Furthermore, some parts get warm, regulators usually do and that's normal. If the amp plays fine, just enjoy it.

Thanks for all the help guys. Im really not sure that stuff is glue, it just doesnt look like glue (or enough to hold anything) and is not on other caps. Ill soak test it some more, but i think the possibly faulty parts might actually be for the phono section and not something i need so i might remove the pcb and trace the layout more accurately.
