Yup, as the temp climbs the output drops some. Even though I'm glad I got the
solid state amp I still prefer tubes, hi. The drop is anywhere between 100 to
maybe 300 watts.I never really noted the exact numbers.

p.s. I'm thinking its a normal solid state thing.

I'm using the K3 with the Elecraft interface cable. I've noticed the
the CW drive power required by mine varies considerably, both with
temperature and SWR. If I set the K3 output for a KPA1500 output of
1500 W output initially, the output will drop to perhaps 1100 W when the
temperature stabilizes at around 65 C. (I've ruled out any change in
antenna impedance, etc.) A similar change occurs if the SWR goes from
1:1 to 1.2:1 when changing frequency or switching antennas. I haven't
changed the ALC from the default setting. Has anyone else noticed this?
