I had a similar problem last week Phil. I decided that the KPA3 was toast, so I pulled it out, inspected it with a magnifier for burns, cracks and other. I also took a close look at the tuner and tried the QRP transmitter. When I could find nothing wrong, I reinstalled the KPA3 and everything works (to the tune of a 70,448 160 meter score). The only thing that I can figure is that a pin or two on the drive side of the amp were not making good contact. My power setting reading was normal, but on CW the power quit increasing at about 40 watts out. My other theory is that it is a poltergeist.
