Have a 1974 Session 400 with a low buzz in volume. It's constant and no controls affect it. Buzzes without any thing plugged in. Disconnected reverb at tank. No affect. It's before the molex connector was used and wires go into chassis. Very low volume buzz but bothersome. Thanks, Ken

Sounds like the filter caps are bad. With an amp that old, they're due to be replaced, but it should be done by someone who's experienced in such tasks.
