Don: The Key Down voltages on Q5 were completely normal: E: 0.547 V B: 1.274 V C: 10.26 (12.0 volt power supply)
I also checked the voltages from D1 through Q11 (page 17 or Appendix F) and they are vall OK except that the base voltages from Q6, Q7 and Q8 are close to zero when they should read 1.1, 0.6 and 0.6 Volts respectively. It seems Q5 is working OK but how do I know any signal is comping into that amplifier? The only oddity I have run into is that I read the opposite voltages for Q11 than the manula states i.e I got: E: 1.2 V B: 0.6 V C: 0 This was with key down. I have stared at the device again and again to see if I am reading it backwards but I cannot find my error so far. Thanks for any help.
