Buzzing can be hard to find, you’ll need a multimeter to work out where the overload is happening. I think it’s simple but time consuming, and then getting the capacitor or resistor out isn’t an easy solder either... I did find a strange grounding point on the back of the 2000, a copper strip connecting the circuit board casing to the shell. Bad grounding will cause a hum for sure
