Does the amp have silver grill badges? Does the amp have a 12AX7 tube in addition to the 4 larger output tubes? Taking the chassis out of the cabinet and looking for test and production date codes or labels is usually the most accurate way of dating a Music Man amp, but the answeres to the questions above should help narrow it a bit. One thing is for sure, it was made before 1980-81 as it was replaced by the 150 series in the 1980 catalog (which is posted in the Manuals area of this site). Steve
