[Elecraft] KPA100 no output above 11 watts

[Glenn Maclean]

I just finished putting a KPA100 kit together. All the initial tests 
were satisfactory until I got to the point where it is time to check the 
output of the PA above 11 watts. When I set my K2 above 11 watts I get a 
High Current message with no power out. I set CAL current to 3.5 amps. I 
set the CAL current to 4 amps with the same issue. The K2 works with the 
amp connected at power levels below 11 watts.

Where do I start looking? I have looked around T1 and components per the 
manual. The component values are correct.

Thanks,
