Backstage 30 buzzing
I picked up a used backstage 30 I have significant buzz and it gets more pronounced with increased gain. No guitar plugged in

That amp is old enough to have bad capacitors in the power stage. Have you pulled the chassis and looked it over? Look for bulged or split caps, burnt resistors. Keep in mind that a bad cap can look okay. Could also be a bad op-amp (usually a 4558) or even bad power transistor.
The more I learn the more I realize how much I don't know.
