Hey
My Engl combo starts humming loudly after about 10-15 minutes of functioning properly.
The master volume knob alters the level of hum. The amp hums increasingly more at minimum and maximum settings. It seems to hum the least at about the 11-12 o'clock position, see video: https://www.youtube.com/watch?v=OFRLbeEJ7dE
A few times it has also squeeled while humming.
Does anyone know what's wrong with it and how it can be fixed?
