Good morning Don, I check the voltages on my K2 last night and here are the results. I set my AGC back to 3.746 from the 3.80 this way I could compare your results to mine. With RF gain set to clockwise or full. My voltage readings are to the right of yours.
U2 pin 5 -- 3.74 volts 3.05 volts U2 pin 6 -- 3.74 3.06 U2 pin 7 -- 3.73 3.05 U2 pin 8 -- 8.34 8.05 (note I measured 8 volt regular and it was 8.05v) U2 pin 1 -- 3.74 2.59 U2 pin 2 -- 3.44 2.59 U2 pin 3 -- 3.42 2.58 U2 pin 4 -- 0.00 0.00 Q12 base -- 3.68 2.85 Emitter ----- 3.42 2.58 Collector -- 8.22 8.03 Then with the RF Gain set to full Counterclockwise: U2 pin 5 -- 4.77 volts 3.74 volts U2 pin 6 -- 4.77 3.74 U2 pin 7 -- 4.76 3.74 U2 pin 8 -- 8.34 8.04 U2 pin 1 -- 4.30 3.26 U2 pin 2 -- 4.30 3.26 U2 pin 3 -- 4.30 3.25 U2 pin 4 -- 0.00 0.00 Q12 base -- 4.58 3.53 Emitter ----- 4.29 3.53 Collector -- 8.22 8.03 These are the voltage results and I did remove the control board from the front panel board and examined P1 and J6. I have to give the connector on the front panel a look at but the knobs have to come off so I can get a good look at the board. I hope these readings my help you out with further narrowing it down. Thanks very much Don for spending all this time on the issue.
