I have not been bold enough to actually testing it :-) Download the schematics http://www.elecraft.com/manual/K3_Schematics_Jun_2010.pdf and look for (use Search function) for D28 . 73/OZ4UN -----Oprindelig meddelelse----- Fra: [hidden email] [mailto:[hidden email]] På vegne af G4HUE Sendt: 15. december 2012 13:26 Til: [hidden email] 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.
