Ibanez GTA15R no output

[ca7922303]

Powers on, hums only, replaced 1-transistir with heat sink on it, only 1 on board, not able to find issue. Again, old project, looking for some help to get it out of the way.

Transistor*

Did that transistor have 5 legs? If so, "power amp IC".

I am OK to help, but can I suggest work on one at a time, especially ones that are so similar. What you learn fixing one just might answer enough questions to fix the next on your own.

Yes it has 5 legs, appreciate your help, will get back on it shortly.
