Warranty brands include Carr (USA), Marshall, Laney, Vox, Peavey, Ampeg and others.

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

In the table below, for example, a “JE” date code indicates a production date of May 1960.

In general, Fender amps that don’t have rubber-stamped tube sticker date codes have EIA numbers on their transformers that might enable determination of the production date.

This black-and-silver sticker contains several lines for “sign-offs” on completion of sound and electrical testing.

The final line contains a date code of two printed or handwritten letters denoting the amplifier’s production date by year (the first letter) and month (the second letter).

I'm based in Marrickville, Sydney and prefer contact by phone but will answer emails when I get a chance. About 11AM is a good time or most evenings after 7.30PM.

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.

These stamped letters may appear in various positions on the chart.

For example, EIA 606-4-21 would denote the 21st week of 1964.
