[Elecraft] Strange KPA100 behavior

[Mike Geddes]

Greetings. I recently finished my K2 KPA100 kit. It seemed to work okay 
initially, then last night started to exhibit some strange behavior.  It 
would transmit correct power on tune under 11 watts (and show low SWR), but 
on anything over 11 watts, on tune, it would transmit around 165 watts and 
show an SWR of around 7:1!!  And giving High Current message Is there 
anything I should start looking for initially?

Any suggestions are appreciated.

Thanks,
Mike
