If anyone has an amp with a "PA" stamp, please let us know.Still, I wouldn't be too quick to just glance at that tube chart and accept an "OA" as a January 1965 amp.
Now, we obviously haven't looked at every amp made in January 1966 so this isn't set in stone.Likewise, the brown/blonde Tremolux, Concert, Vibrasonic, Twin, Pro, Super, Vibrolux, Showman, Dual Showman, and Bandmaster used a sequential numbering independent of model, but as with Fender guitars, these were not used consecutively. The 1956 to 1963 Champ, Harvard, Princeton, Deluxe; the 1956 to 1960 Vibrolux, the 1956 to 1964 Bassman, and all the tube reverb units have their own serialization scheme.The Champ has a "C" prefix, the Harvard an "H" prefix, the Princeton a "P" prefix, the Vibrolux a "F" prefix, and the Deluxe a "D" prefix.These say "Fender Electric Instruments." Depending on the model the use of these pre-CBS panels have been observed on amps as late as August 1965, except for Champs and Vibro Champs which had foil stickers on the back the chassis.Fender must have had a million of these labels printed up since they appear on Champs and Vibro Champs well into 1966.The biggest tip off would be the control panels which brings us to interesting factoid #2.
After CBS bought Fender in January 1965, there were still plenty of control panels for various models that were in stock.

It's been about 6 months since Part 1 of this series was printed so I thought it would be a good time to give an update on the Fender amp research that I am doing along with Devin Riebe and Greg Huntington.
Preliminary results show that we're on the right track.
Here's a couple of examples using the tweed Deluxe (model 5E3) and the Super Reverb/Bandmaster Reverb.
