Question about my Art SLA-2

[Stringtheorist]

My SLA-2 hums. This isn't noticeable when I'm playing, and doesn't get louder as I raise the volume but it's somewhat annoying when idling. Is this normal?

Same thing here. It's constant and not loud, but annoying in silence.

Thanks. At least I know it's not faulty.
