I would start with the voltage at the source of Q18. Actually the high
voltage is just the indicator of the problem, Q18 is not faulty, the
resistance between the source and ground is the problem. You should
measure close to 270 ohms, but I would think you will find it higher
than that.
So I have a K2 all put together. I thought it was receiving fine - I didn't
try transmitting as I shamefully don't have CW down yet. I got the ssb kit
and put it together and it didn't transmit. I stripped it out (jumpers back
in place at W2, W3 and C167 is back in) and tried testing cw
