[Elecraft] Power has disappeared

[Chris Kimball]

I'm a new owner and all worked fine.  After an absence of a few days I came
back to no power out, or , at least, very little.

Rig is the 100W version with ATU working into a dummy load.  In CW mode
adjusting the power level to 70W produces only a one segment power out.
Running the ATU produces a 5W indication, the usual searching rumbling, but
no resultant SWR. The Test mode is NOT in operation.

I have restored to the last working config via K3 Utility, but suspect I
must have "hit" something to limit the power.  The FP and AMP temps were too
high (35C) when the problem was noticed. I set them down to a more
reasonable 23C without effect. Input voltage is 12.8V.

Probably something trivial, but suggestions would be appreciated.
