Thank you. I will do the transistor voltages this afternoon, if I can locate them on the board. As you know, the board isn't marked with component numbers (Q1, C5, R12, etc) and the quality of the service manual and board diagram I'm using is not good...very hard to make out part numbers.
EDIT: Pulled up the diagrams on our desktop PC with the big monitor, and can read it quite a bit better now. Unfortunately, the PC is on the 2nd floor and my workshop is in the basement...but I can use the exercise!
Mark, as I was locating the transistors to be tested, I just wanted to verify that the first pair to be tested is Q16 and Q17. The "matching" transistor for Q17 - in terms of position in the circuit - is Q18. And, the "matching" transistor for Q16 is Q15. So, just wanted to verify that you indeed want me to test Q16 and Q17, since they have different places in their respective circuits.
