I would personaly suggest to find a service center or a very good local tech who can do audio amplifier and reciever service.

Look for low valued resistors that may look ok, but be open. Check the emitter resistors (.22 or .47 ohms). Check the transistors in the driver circuit as well.

Yes you can use either A or B without a problem. The restriction is when you have both A & B connected. In that case, the speakers MUST be a minimum of 8 Ohm impedence. Using either A or B, you can use speakers of 4 Ohms impedence.

most common on all such it dry joints on the main pcb.
all such items run pretty hot and after a few years one has to remove the main pcb and resolder all dry joints or complete pcb, to prevent resolder.
Best do the complete pcb to prevent future failures.
