On the second return their engineer tuned it 2 MHz high so when it heated it would be right on channel, the fourth return he put in 500W capacitors, then it blew the transmitter and is back in Phoenix for a fifth repair.
About the only thing I can think of that might be an issue is the elevation of 7400 feet, but I have left it at full power for 6 hours and the outer casing is just warm to the touch.

Something is wrong... Things to look for are under sized
loads, the wrong type of metal mounting hardware, out of
tune operation and cooling issues. Under power the
circulator will change tuning, heat can cause it to really
change. You should have at least some modest air movement
past a circulator with >50 watts through power.
The load can run hot, but not past its max value. Over
35 watts the better load connection is external from the
main cirulator body to keep heat away.
The amplifier should have both voltage and serious current
protection to prevent damage.
