[Elecraft] KLPA3A power transistor thermal stress concerns

[Ignacy]

Seems a bit artificial problem, unless someone is driving an amp that
requires 12 W. My modified Expert 1.3k-fa requires about 6W to 8 W for 1 KW
output.
 
If a serious concern, increase voltage to 15V. The Yahoo KX3 group has
graphs of IMD3 as a function of power and voltage. Increasing voltage at 12
W by 1 V decreased IMD3 by about 10 db. I assume that the LPA in K3 is
similar to the amp in KX3.
