First, Thanks so much for the replies, helpful advise and questions. I had a friend who knows how to use the Oscilloscope look at my OpAmps and he believes those are fine. But perhaps I could look at replacing the switch and volume pot. Also, I do not have the schematic, which is something I've been looking for forever. If you have it, that would be awesome (at least I could compare the written schematic with what I can observe of my actual board)! Otherwise, it will be very tough to trace through the board.
Again, very much thanks guys
