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.

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.
