[Elecraft] ERR 12 V message

[todd ruby]

I just got this error message for the first time on my K3 after a normal tune up on 20M. Now I have no use of the KPA3 and the the LPA I running at 75° C! Not good. I also received the message telling me to check the circuit breaker. The three FETs on the LPA are 6 months old and mounded with the correct heat dissipating washers. 

I had been using the radio earlier in the day and operation was perfectly normal

Any guidance?

Thanks
