Well, Yet another fault in my shack the K3 decided to stop putting out power over 12W this last night and came up with the Error "12V ERR" so off to the internet to see if it was an easy fix, well yes and no.
Turns out i is a common problem in older K3 mine is 891 not ancient but older and as the previous owner was a contester probably worked hard. The fault was the discoloured pins on P67B on main board from high current, The older units did not have gold plated pins. The entire rear end had to be disassembled but pretty easy. PA removed and the PAIO board , anyway this is probably not new to the group but I must say the modular design simplifies the repair. After replacing the six blackened pins from parts left over from my K2 build all good. Not to mention the step by step repair here http://www.elecraft.com/manual/KPA3%20Power%20Connector%20Replacement.pdf So now the K3 after reassembly back up and running. Now back to fixing my K2 which hasn't even been on air yet. 73 Cliff ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
