When you get the cover off, post some nudies of the innards. If you have another power amp handy, check if both sides of the preamp section are working.

If you have blown diodes in the power supply replacing the diodes may not cure the problem. You need to look for something pulling excessive current throught the diodes.


Edit:
If forcing those RCA jacks apart made the amp work properly the chances are nearly 100% that you have a bad solder joint. Any corrosion that gets on an RCA jack will usually get removed by the action of plugging in a cable.
