These units look, and apparently sound, just like the Schumacher-made units so it’s easy to overlook that “831” code.
Working at FMI – I was able to interview a fellow (who wishes to remain anonymous) who worked at Fender in 1972-73 in the amp department.
Of course I tended to hurry more when they were there, and I would fumble more, too.” Another really interesting fact was that he recalled that the eyelet boards were loaded/wired/soldered in Mexico!
“I remember the circuit boards were pre-made, from Mexico, easy to screw into the chassis. When we had filled our cart we'd wheel it over to the Chicano chicks.
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.
There is some debate about how to interpret the production code information on late ‘50s to mid-1967 tube charts and Greg Huntington is still working with those.
I have to wonder how often Fender used the SPEC check box and what features a “special” amp or cabinet would have?!
