Note the check boxes for DOM (domestic US model), EXP (export model), CSA (Canada model), STD (standard) and SPEC (special).
I have to wonder how often Fender used the SPEC check box and what features a “special” amp or cabinet would have?!
He recalled, “We just went to a big bin every morning and loaded our wheeled rack with a batch of whatever chassis we were working on that day.
Also, another thing I’ve never seen before is a what appears to be a shipping tag of some sort (see photo).
These are marked with EIA code “831” and are most prevalent during the 1966-68 time period.
Some examples include a '66 Princeton Reverb and ’66 Pro Reverb with Better Coil output transformer, a ‘66 Deluxe Reverb and ‘67 Twin Reverb with Better Coil reverb transformer, and a 1968 Vibro Champ with Better Coil trannies.
One has to wonder where all those factory original export back panels are! Another interesting tidbit is that a lot of Fenders were imported into Australia in the late 1950s and early 1960s that were stock 110-volt (domestic US) units.
The Australian Fender Distributor then installed 240V - 110V stepdown transformers in the bottom of the cabinets.
A 1957 tweed Vibrolux was reported with a tube chart printed with circuit “5E3” (tweed Deluxe) instead of the correct 5F11 (see photo).
