Mid ’70s – early ’80s – Amplifiers are dated much the same way as Fender guitars from the same era:

B + 5 digits 1975 – 1976
A6 + 5 digits 1976
A7 + 5 digits 1977
A8 + 5 digits 1978
A9 + 5 digits 1979
F0 + 5 digits 1980

F3 + 5 digits 1983 – 1984
F4 + 5 digits 1984 – 1985

Dating Contemporary Fender Amplifiers

All Fender amplifiers manufactured from 1990 – present include a date code printed on the quality assurance (QA) sticker on the back of the amp chassis, and are dated the by the first letter as the year and the second letter as the month.

A 1990 JAN
B 1991 FEB
C 1992 MAR
D 1993 APR
E 1994 MAY
F 1995 JUN

ALL other Fender Amplifiers can be dated by the components inside:

In almost every Fender amplifier there are several EIA (manufacturer) codes followed by a date code, typically found on the speaker(s), transformer(s), tubes, caps, and occasionally pots. The EIA code will consist of 3 numbers followed by a date code of 3 or 4 numbers designating the year and the week. To give an example, a typical Oxford speaker from the ’60s will look something like: 465-217. 465 designating the Oxford EIA code, 2 designating the year 1962, and 17 designating the 17th week of ’62. Take a look at this ’62 Fender Princeton Amp, and you’ll see that exact speaker, as well as the typical Schumacher transformers (EIA 606) used in Fender amplifiers.
