Question about Crown CE2000 2-Channel Amplifier
I had one that was doing that, and it ended up that one of the screws through the main board into the chassis was loose and was not making a good ground connection. Gently loosen and retighten the screws that hold the main board to the chassis.

The hum is power line hum ( 60 cycle ) . It may be that when the amp gets warm that something in the case wants to vibrate to the 60 cycle hum.
I have amps that hum like that and theyre fine.
Depending on the design of the amp, the cooling fan may not go on till it gets really warm in the amp. Some run all the time like the Ashly I just fixed
