Flashover in linear amp fed w. K3

Pentti A J Pajunen
Hello Elecrafters!
Happened one day when tested Drake L4, that there was a loud bang in the
linear causing electrical shutdown in both, the linear and the K3. Now
seems that the K3 refuses of any output, RX normal. Hopefully the cause
is only corrupted firmware, still having a fear for damaged transmiiting
cirquits. No PA output no output when the PA is deactivated. Bricked?

This happened to me last week, although it may not have been a
flashover.

Have you power cycled the K3?

Mine would not output any power after the KPA500 faulted, even when I
turned the KPA500 off. No barefoot power, zilch.

I power cycled the K3 and all restored itself.

73,

Alan. G4GNX
