Marshall used letters as a date code to represent year of production.
It's important to note that, prior to 1984, this letter came last.
From January 1965 to June 1969, model codes were used but no known serial numbers accompanied them.
This era saw the advent of Plexiglas panels (giving rise to the "Plexi" name) and four-digit model numbers.

To find the serial number on your Marshall amp, start by looking at the back panel of your amp.
Starting in August 1997, Marshall moved to their current serial number scheme, which is easier to understand and gives more information than previous schemes.
These current serial numbers are arranged in a letter-ten digits-letter format (A-xxxx-xx-xxxx-A).
These are still found on stickers with a bar code on the back of the amp.
While Fender and Vox amps have their place in moving electrified guitar forward, the creations of Jim Marshall fostered an entirely new sound and allowed guitarists to fill stadiums with it.
Marshall amps had such precedent-setting wattage and tone that their history can hardly be separated from the history of rock itself.
For models made between 1979 - 1981, the serial number will be on the front panel.
