Music Man 130 Diagnosis Help

Music Man 130 Diagnosis Help
Hi Everyone, I just got a MM 2x12 130, 74 model with 4xEL34+ 1 12AX7. It works fine but seems to have low power and breaks up faster than other MM's I've had. It's fairly gainy for a MM, similiar to a MV Marshall. I put in new tubes, peeked at filter caps, they looked OK but I jumped one of the 100mf w/another 100, no change. Any suggestions?  
Regards, Ethan
