The FT-817 PA seems to be prone to overheating.
I have been running the 817 on 13.8V till now, and since it runs fine down to about 9V, I am thinking of finding a 10V regulator to take some heat out of the equation.
Will be looking for a 7810 IC, or possibly using the LM317 for that purpose.
More soldersmoke coming out some time here.

it a try on...
