My Marsha hums even on standby

[FAN HALEN]

Is this normal? It's not a loud hum but certainly noticable. It's coming from the amp itself and not through the speakers. Let me know if there's an easy adjustment.

Thank you!!!

This is common and there's no adjustment.

It's normal, it's the nature of the transformers

My Metro 12xxx w/Friedman mods does as well. It's like a bleed through to the cab. Weird, but I guess I don't really care. The amp sounds so damn good...
