Question about Marshall MG100HDFX 100-Watt Amplifier Head
Some cooling fans are "throttled" depending on the sensed temp... these CAN be noisy upon initial startup.
It can also be bearings going out... best plan is to watch it and see if it gets worse.
Changing a fan is fairly easy. You have to observe the polarity of the connections. Replace with identical unit.
