"My KPA500 is showing 57-58 VDC at 450-500 watts out, and 71-72 VDC on rx."
That's a much smaller spread than I see with my KPA500. Are you powering from 240 VAC or 120 VAC? Running on nominal 120 VAC I have my RX PA volts currently reading 81.8 and it still sometimes sags just below 60 V on TX. Note that the drop is not related only to power output but is a function of total PA input power. PA efficiency varies with band, output power, and antenna match.
