[Elecraft] [K3] Power variations in K3 / 3.19

[Ignacy]

After lengthy QSOs and after slight retuning, power from K3 drops to about
1-2W and the radio draws about 3A. It is still set to 110W and cranking the
power down and back does not change anything. Same after QSY to another
band. PA temp shows 35C. A few minutes later the power is back. This problem
is new and may be peculiar to 3.19.

There is an old problem still present on 3.19. AFter turning the rig on, in
SSB the peak power starts at 30-70W and in a minute of transmitting rises to
about 95W (when set to 110W). Measurements with LP-100 calibrated in
factory.  The initial power varies from time to time. 

Any ideas?
