Good advice. I run my KPA500 with all the lights lit in all modes, including very aggressive RTTY contesting As noted, the fan speeds up with constant CQing, but never approaches maximum speed. I also run it this way for various WSJT modes, with the same performance. The wattmeter, which I have not calibrated on the HF bands, says I'm getting 650-700 watts. The amp is quite well protected.
