Sebastian, Glad it worked out. I was suspecting the KEY-OUT transistor when I suggested testing with no power applied to the K3. So two things learned - Elecraft Support is superb and you can fix many things yourself (with a little help).
An as a young technician an old mentor told me that in troubleshooting, don't assume the worst. Most things that fail are simple and simple to fix. Another tech I worked with taught me this lesson in a different way. I always did well with logically looking at the problem, but often he would find the problem quicker. He used the look, feel, sniff method. Didn't take brains just giving good attention to what often was obvious. In Sebastian's case the KEY-OUT transistor was overloaded at some point and shorted out. One has to be careful what they connect to circuits like KEY-OUT that the current limits are not exceeded. Keying a small relay is good insurance as a relay can handle higher current or voltage with less risk. Happy Holidays!
