From my friend Libra :

These voltages make little sense given that R4 || R7 is 165K and R6 is 220K. Average Q1-Q2 collector voltage should be in the vicinity...

"smoke gets in your eyes..." Ahh wrong thread, this is more appropriate on Gene's name that tune thread.

Good that you ruled that out as a culprit. For safety's sake, I would recommend reattaching the lifted leg on each diode.

:eek::eek::eek:

You may want to try lifting one end of both D9 and D10 to disable the protection circuit to see if it is complicit with the bring up...

If those are the original TIS97 back in place, that looks correct, it is more the difference in Q3-Q4 that should be confirmed...

Are you sure that when you found this barn find that the board had not been worked on prior to you finding it? The reason I ask is that...

Probably true Eric. The lab has very efficient A25 monitors and they can very easily drive me out...
