Chuck, I had a quite similar problem. My K3 was qrp waiting for the KPA3. When pushing tune I had full power (12W). Talking SSB I had full 12W but when I touched the power knob, even reducing 0.1W caused the power to drop to 8W peak. I had to retune to resume full power. I checked the LPA twice but at last I noted that it wasn't fully inserted. I pushed it firmly and now is working fine. Ciao
