jk- Seeing as the burn is on the outside of the transformer, I wouldn't worry about it. Looks like it just burned the coil insulation wrap. I would clean the burned area off with alcohol and carefully inspect the coil windings in that area just to be sure the windings didn't short together.
As far as "No music until I power off" goes, the amp may be biased way too low in current, causing it to be in cutoff mode. Once you turn the power off, if the bias voltage falls faster than the main B+, it may bias itself into the correct region momentarily. Set your bias for 70% Plate Dissipation and try it again.
