Just a notice to those working on ST-140 power amps. I've come across a resistor labeled on the board as R10. This resistor does not show up on the 1998 schematic diagram that's available. It seems to be between the base of transistor Q8 and the collector of Q5. The value tests at 22 ohms.
For whatever reason, the schematic jumps from R9 to R11, and does not show R10.
Just a heads up for anyone working on these amps.
