It is on the somewhat large, stand-up sink-- and it is in a TO-66 case,, near the middle of the chassis. It runs on pretty high voltage--for a transistor--about 150 volts or so--IIRC. I'll have to look in my manual for my 2000 to find out for sure--since the audio output circuit is the same--only that DC volume control BEFORE the audio preamp IC is different. The preamp IC drives the transistor--and it drives the output transformer--and then the speaker.

These HV NPN transistors are known for their tendency to "break down" and not produce any output--or little output or scratchy sound. That is a Class A amp--and it runs HOT--regardless of the volume setting--and so...they sometimes "die' after some time.

Check the collector of that transistor and see if there is apprecible voltage there--I KNOW it is over 100 volts. if NOT...check and see if that emitter resistor is open--and if it is....the transistor has likely taken a dump. Particularly--if the sound just "quit"--that transistor is suspect.

One way or another--we CAN walk you thorough getting that ol' girl "talking " again.
