These are marked with EIA code “606” which is the company number for Schumacher.Well, this universal “truth” was debunked when we found a bunch of amps with transformers made by the Better Coil and Transformers company.The EIA assigns each manufacturer a three-digit code (there are some with one, two or four digits).When dating an instrument by the ‘pot code,’ keep two things in mind: The potentiometers must be original to the piece (new solder, or a date code that is off by ten or more years is a good giveaway to spot replacement pots); and the pot code only indicates when the potentiometer was manufactured!

The CJ-3A had many features similar to the late CJ-2As.
Likewise the late CJ-3A had some of the new characteristics of the CJ-3B. These differences can be used to roughly date when a vehicle was manufactured.
A 1957 tweed Vibrolux was reported with a tube chart printed with circuit “5E3” (tweed Deluxe) instead of the correct 5F11 (see photo).
Clearly Fender wasn’t afraid to use incorrect parts when they were in a bind. The 5G12 Concert is the earliest version from very late 1959 and early 1960 so the existence of a tweed example, while extremely rare, is certainly plausible since Fender was making lots of tweed amps during the same time period.
If the code does not fit the above criteria, don’t force it and skew your dating results.
