These 1965 codes begin with the letter "O." The code for the year 1966 is "P." However, someone in the factory apparently forgot to switch the stamper from "O" to "P" in January 1966.Therefore, amps from January 1966 have the date code "OA" (A denotes January) in green ink.We combined all of our information into a computerized database for this project and for the past 18 months have been slowly (sadly, very slowly) gathering information that we collect ourselves as well as from other people. What we need is the following: 1) Model name 2) Model number on the tube chart 3) Date code letters on the tube chart 4) Speaker codes (if speaker is original) 5) Transformer codes (if the amp doesn't have date codes on the tube chart) 6) Cosmetic features (flat/raised logo, tweed/tolex, blackface/silverface, rough/ smooth blond tolex, white/skirted knobs, TV-front/wide-panel, etc.) One very interesting and very important factoid has surfaced regarding the date code letters on the tube chart.In the fall of 1965, Fender switched from stamping these numbers in black ink, to dark green ink.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.
These appear to be used sequentially independent of model.Our evidence is that we are finding some serial numbers duplicated between models.For example, serial number A00121 has been found on a Champ dated November 1964 and a Vibrolux Reverb dated February 1965.This makes things a little more interesting and difficult in playing the "dating game." And yet there is another variable to contend with as it appears that models that share chassis may also share the same serialization scheme.For instance, the Bandmaster Reverb and Super Reverb share the same chassis, and the Twin Reverb, Quad Reverb, Dual Showman Reverb, Vibrosonic Reverb, and Super Six all share the same chassis.
Greg and Devin's experience meshed well with mine since I'm essentially the blackface/silverface amp guy (amps made between 19) in the group.
