I quickly tried the hair drier method tonight but it's inconclusive, I need to spend more time at it. The hour I have between when I get home and need to go to bed isn't enough. I may have a few hours between shifts tomorrow so I'll see if I can learn something more definitive.
I failed to consider that most of the transistors are not exactly easy to get at so instead of tapping the transistor's body, I had to tap directly below it on the PC board's foil side. What I think I found is that one seemed to produce a reaction and it is on the right channel but if I understand the manual, it is located in the phono 2 section. At the moment, that makes no sense because the noise generated was not affected by the input selector or anything else.
As I said, I'll spend more time with it tomorrow if possible.
That Cold Spray, I've seen it but never tried it. If I got a can, would just the act of spraying a transistor be sufficient to make it go noisy? Or is it cool then heat or heat then cool?
So far, and with magnification, I have been unable to read the part number directly off the transistor. Maybe the light in here will be better during the daytime. BTW, the mind is not the first thing to go, it's the eyesight. Someone sent me a PDF service manual but once I expand the drawing large enough to where I could normally read the printing, the resolution is too poor to make out the characters.
