Hello folks, I got this amp and someone had messed with it before. Looks like they tore off a transistor and I cannot find a service manual to tell me what it was. Can someone help me make maybe an educated guess? It is the one circled on the left of the first photo. I am guessing it is the PNP version of the CR533 such as a 2SCAR533D but not sure. Is it possible it is another NPN like the CR533?
