This sticker is a chart that shows the types of tube types used and the order of their physical location in the amplifier, and may be rubber-stamped with two-letter date codes that denote the year (first letter) and month (second letter) of production.

The first letter is the year and the second letter is the month. If the tube chart is not in the amp or has been torn or damaged and you cannot read the ink stamped letters you can date the amp by the codes on the potentiometers.

Below is a chart of the manufacturing codes for potentiometers.

Several different types, in vertical and diagonal weaves, were used.

Please note that it’s quite difficult to precisely determine the production date of early Fender amps.

Although the dates derived using the charts below will likely be a good approximation, they should not be considered exact.

All Fender amplifiers manufactured from 1990 to the present include a date code, printed on the quality assurance (QA) sticker on the back of the amp chassis.Remember, your amp is newer than the newest component.For example, if you find pots from late ‘64 and transformers from early ’65, you can be pretty sure your amp is a 1965.For example, EIA 606-4-21 would denote the 21st week of 1964.It is also advisable to add about 6 months to the date to allow for time these parts may have spent in inventory storage.These numbers always begin with “EIA 606,” and are followed by three or four digits in various combinations.
