Transition era Bandmaster with original blackface AB763 circuit. Head only; the cab is sold. Chassis date stamp, #171168, indicates amp was built the 11th week of 1968 = March 11 - 15, 1968. (Silverface circuits were not introduced until Fall, 1968). New electrolytics and power resistors. Any leaking coupling caps and resistors that drifted more than 10% from original values are replaced. All tubes are good. In other words, this amp is reliably ready to gig.
