Andy  there is a Zener diode (BZW50-15) protection. 
I have not been bold enough to actually testing it :-)

Emne: [Elecraft] K3 overvoltage protection 

Hi guys, I am a new owner of a K3 serial number 6990 (must say I am mighty impressed by it) and considering its cost I wondered if it had overvoltage protection. I dread the thought of destroying my K3 due to PSU failure! I have searched the past postings and cannot find anything relevant to the K3. 

If not I will make up ma "crowbar" circuit.
