The older Music Man amplifiers that have the 12AX7A phase splitters have the SILVER badges. The Black badges are the later series and have the solid-state phase splitter.
The black badges weren't introduced until late 1979 or early 1980, so your amp may be a year or two newer than you think. I have a 1979 410-65 and it has Silver badges but a solid-state phase splitter.
On those amps so equipped, the 12AX7A is close the the power transformer and in plain view.
