I just put the reverb board back in the k100 and hooked up a good reverb tank and have spring sound loud and clear if you tap on the tank. There is no reverb effect getting through from the preamps. Checking against your readings, most of mine are close or above with the exception of Q-801. I'm way off at the collector. I'm getting -8.8 and +9.0 on the voltage supply lines and the readings I get from Q-801 are E= -7.95 B=-7.24 C= -7.46 there is a resistor and cap hooked to the collector and R829 registers 1.1K and the cap is not shorted. I already replaced the transistors in this section with those 2N5089 and pin them according to the data sheet. My multimeter has a transistor tester of some sort on it. There's a square box for inserting these small 3 pin transistors, the top half for NPN and the bottom for PNP. It gave me a hfe reading in the E/B/C direction of 684. Guess I'll replace that cap and resistor next.
