The date is in the last three digits, after the —. The first of the three digits tells us the last digit of the year unfortunately not decade specific and the last two numbers tell us the week. In the above example, the transformer was made in either or , week This code can be found on the power transformer, output transformer, choke, and reverb transformer.

This article updates information from research started in and most recently published in The progress of this type of work is slow, hence the long hiatus, however, a lot of new data have been collected regarding Fender amplifiers, including production numbers. Advances have been made with regards to the production of tolex amps and it appears that much of this information can be applied to late s tweed amps as well.
In addition, the dating-by-serial number tables have been revised and are more accurate. The bad news is that there is still a lot of work that needs to be done on the silverface amps. Unfortunately, there is some sad news to report as well. Fellow Fender amp researcher, Greg Huntington, passed away June 5, after losing his battle with cancer. Greg kept his illness very private, even from this author.
His passing is a great loss to this research team and the Fender amp aficionado community in general. Greg was passionate about Fender amps and his knowledge, insight and humor will be missed very much. Paul Linden has volunteered to fill in for Greg.

Here is a cool link to a Vintage Fender Amp price history chart that tracks sales data for specific amp models by the month.
Expanded Manufacturer Code Chart EIA Source-Date Codes: Electronic components such as transformers, potentiometers, speakers, and some capacitors are often stampted with a date code indicating who manufactured them and when. Remember, your amp is newer than the newest component. So if you find pots from late 68 and transformers from early 69 you can be pretty sure your amp is a Check out this Google search for more resources.
Circuit Code: In Fender stoped using model numbers to identify schematics and began using the model name and an assigned circuit number. These circuit numbers which are located on the tube chart can be usefull for getting a rough date on an amp. Fender often used the same circuit for many years so this is not a very accurate method for amp dating.

Mid-seventies Fender amp dating is kind of a crap shoot. Fender always had a zillion different parts that they would assemble into the amps they sold that year, and that phenomenon only increased in the seventies.
