Played a gig last night with my 2061X RI plugged into one 1974CX cab. At the end of the night, right before the last song, a loud high pitched squeal came out of the amp. Turned it off, turned it back on, squeal was still present. The squeal went away when I turned the volume on the amp down, then the squeal came back when I turned the amp's volume back up. Plugged directly into the board and finished the gig. Today, brought the amp into the house, plugged it in using the same guitar as last night and it's fine. No squeal. Last night while driving home I thought maybe I fried the OT or fried a tube but today all is well. Anyone have ideas what could have caused the squeal?
