Don and Nick,
Doesn't the K2 drop the power to 2 watts during tune? Or am I thinking
of a K2 with the ATU?
I know that I was bitten by this once - I thought something was wrong
with my K2 when I was
trying to tune it up with a new antenna and I had a power meter in
line. I had set the K2 to 5
watts and it was only putting out 2 watts in tune.

With both low power out and low current drawn, there is clearly not enough
energy being developed by one of the transmit stages.
If you have not already, build up the RF Probe that came with the K2 kit and
do the Transmitter Signal Tracing steps detailed in the Troubleshooting
Appendix of the K2 manual. Once you locate the stage where the RF Voltage
level is significantly lower than that which is expected, the problem will
be just before that stage.
Once you have localized the problem to one stage, we can help you localize
the component at fault.

K2 #5209, Set at 5W, TUNE, I'm drawing only 1.0A, and should expect 1.3
to 1.6. Similarly, set at 10W TUNE, I'm drawing 1.02A, not 1.8 to 2. I'm
pretty sure I'm not putting out the power I should be, and DL1+DMM also
implies I'm only putting out about 2-4W, not 5-10. This would be at
7100kHz during 40m TX alignment. Is there some way to calibrate the
power output using DL1 and my DMM, or have I built something wrong?
