My beloved K3 is giving me fits. It was recently returned from Elecraft service for some 8v regulator capacitor replacements. This was done in April. I have been operating the K3 on just a few occasions since then. Last night when attempting to tune up, the radio would shut down if the power output was set higher than about 20 watts. At lower power levels the radio would tune. SWR on two different antennas was <1.2:1. The display also showed significant dimming even at low power tune up attempts.
I have done a factory reset per the manual and reset the parameters in the Config menu. I have done the reset twice. I have switched out external power supplies (from a Samlex 1223 to a Powerwerx SS-30DV). I have fabricated a new power supply cable from the supply to the radio; still no joy. Before contacting Elecraft service, I would appreciate any suggestions of something (obvious) I may have overlooked.
