A couple days ago, I stepped out of the shack for a few minutes and upon returning found the KPA500 had shut down. I didnt note any brief power outage, and Im quite sure it was ON when I stepped away.
It has been a little quirky in keying since that time. Yesterday it gave off a funny smell and the Power and SWR LEDs were jumping up and down for no apparent reason. The display screen jumps to frequency readout when I key the exciter, no matter what it is set for. The KAT500 seems to be working normally with the amp either OFF or in Standby. I did a total power reset and reloaded the current firmware (v01.54), but no change. I have not pulled it apart yet, but I seem to remember these being the symptoms discussed some time ago that required an LPF rebuild. Somewhere along the line, Elecraft switched to a SM board and thats when the trouble started. So my question besides asking for general advice is if anyone knows the serial number when Elecraft made that change. My KPA500 is s/n 03835.
