While dating Fender amps made before 1994 by serial number is all but impossible (as records of these numbers were never kept), all hope is not lost—the charts below should prove helpful in dating your Fender amp.
First, it will be useful to you to understand the following five terms in order to choose the correct chart for dating your amp: refers to the two-tone woven fabric that covered many early amplifiers.
Vacuum tubes, or thermionic valves, are arrangements of electrodes in a vacuum within an insulating, temperature-resistant envelope.

On early amps, this material was varnished to make it a more durable covering.
Several different types, in vertical and diagonal weaves, were used.
For most purposes, the vacuum tube has been replaced by the much smaller and less expensive transistor, either as a discrete device or in an integrated circuit.
and Canadian English) or (thermionic) valve (outside North America) is a device generally used to amplify, or otherwise modify, a signal by controlling the movement of electrons in an evacuated space.
The resulting negatively-charged cloud of electrons is called a space charge.
These electrons will be drawn to a metal "plate" inside the envelope if the plate (also called the anode) is positively charged relative to the filament (or cathode).Replacement tubes and transformers are readily available for these amps however there are many boutique amp manufacturers making new tube amps with a vintage sound.A transformer is an electrical device that transfers energy from one circuit to another by magnetic coupling with no moving parts.The electrodes are attached to leads which pass through the envelope via an air tight seal.On most tubes, the leads are designed to plug into a tube socket for easy replacement.The result is a current of electrons flowing from filament to plate.
