Hello, I am new to this forum and in hopes to finding an answer to my dilemma.
I have a Rotel RB-850 with a blown or not working left channel. Once I opened the unit I can see the PSU caps are leaking. The following is written on them
HPS
50V 10000uF
N.C.
NEG. BLACK
TOWA
87113
Can anyone suggest a replacement for these that may work better or should I use identical replacements?

Leaking ? or glue ? Many large caps are secured with a brown glue to prevent stress/movement cracking soldered joints and/or loosing the "rivets" that large caps sometimes have securing the solder tag/pins to the internals of the cap.

It is brown and may be glue I cant be sure. what else should I look for to correct the problem? I have power to the board and fuses are good.
The brown matter is glue, don't worry about it, although it is known that it can corrode components' leads. So check all components that are in contact with that glue. Have you checked fuses?
Back up and running thank you all for the tips. It had something to do with the glue, I removed all traces of it from the board and the components it came in contact with. It now works as it did. I am not sure it it was a slight short or just not allowing a component to do its jub but the end result is it is working now and the corrrosive cunducting glue is completely removed from my circuit board.
