[Elecraft] K3 suddenly dies

[Don Wilhelm]

Gary,

One thing to check is the tightness of the screws for the supply output 
terminals.  If one or both are loose, I recommend removing them 
completely and cleaning the contact points on the inside of the power 
supply.  Tighten everything else up too while you are at it.

You don't have to work on a live power supply - unplug it first.
