I run both of mine full power on RTTY. Fans occasionally come on full speed (control on Auto) but my amps are in a closet (not on the desk) so the noise is not an issue..
I believe the spec is 10 min on, 5 min off at full power. The amp is well protected against temp and swr so I wouldn’t worry.

What is the power level that others have used, fan levels and long term affect on the power transistors? I ask, as so far I have run the amp at no more than 300 watts with the fans at there highest level. I do not want to harm the power transistors.
