These units look, and apparently sound, just like the Schumacher-made units so it’s easy to overlook that “831” code.
The Australian Fender Distributor then installed 240V - 110V stepdown transformers in the bottom of the cabinets.
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.
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?!
