Mesa/Boogie has never published a serial-to-year table, and its serials run sequentially inside a model rather than across production, so a number identifies the model block instead of the date. The authoritative date is written inside the amp: a hand-written month and year between the preamp tubes before 1990, and a technician's initials and date beside the serial decal from 2008–09.
Boogie began with Randall Smith modifying small Fender-style combos, and the original Mark I chassis of 1971–1978 carry an A-prefix number from A-001 to A-2999 on an adhesive label beneath the speaker output jacks.
The Mark II family established the practice that still defines Mesa dating: a month and year written by hand between the preamp tubes on the underside of the chassis, often with the initials of the technician who worked on it.
Serial numbers move onto a decal, in time placed near the mains inlet, with a prefix that identifies the model. The maker's own reference table runs to some 60 model, prefix and position records.
From 2008–09 Mesa technicians initial and date the amps in plain view next to the serial decal, which restores an external witness that no longer requires opening the chassis.

17 Mesa/Boogie models are catalogued with their production years, specs and safety notes.
Browse the models →Mesa has never published one, and its numbers are sequential per model, so one model's sequence says nothing about another.
Before 1990 it is written by hand between the preamp tubes on the underside of the chassis, occasionally inside the chassis.
Mesa technicians began initialling and dating the amps in plain view next to the serial decal.
No. The serial narrows the model and its block, while the written date gives the year.
