Have a new Mark V only about 6 months old. I turned it on at band practice yesterday and heard a small static sound what sounded like it was coming out of the back right side but I'm not sure which exactly. I looked quickly at all of the tubes and didn't see anything out of the normal. The sound went away after a few seconds and never came back. The amp worked flawlessly the whole rehearsal. Anyone know what this might have been? The amp hadn't been cranked or turned on even for a few weeks before yesterday so maybe its just from sitting for a bit?
