Dating Fender Amps

1951-1967 – Tube chart on the inside of the amp is stamped with two letters (A – Q):

The first letter designates the year and the second letter designates the month.

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
F1 + 5 digits 1981
F2 + 5 digits 1982 – 1983
F3 + 5 digits 1983 – 1984
F4 + 5 digits 1984 – 1985
F9 + 5 digits 1979 – 1980

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
G 1996 JUL
H 1997 AUG

J 1999 OCT
K 2000 NOV
L 2001 DEC
M 2002
N 2003
O 2004
P 2005

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.
