While I am NOT one of the more "proven" people around here.... I would be tempted to say that TR23 looks shorted....but find it odd that you see 9v on the emitter when there are only 8v measured on the collector. It would be interesting to pull it and give it a back to back test with a meter....

And, I don't believe that bypass cap would have anything to do with the high emitter voltage in this case. If it were leaking... it is conceivable that it could pull the emitter "down" from where it should be ...but would have no way to push it higher.....especially that high.

This second look has got me wondering about the emitter resistor though... perhaps check it and make sure it is not open or WAY high in value.....
