Also note the vertical black lines on the control panel (found on earliest silverface amps) and the large ceramic power resistors coming off the power tube sockets which indicates the AB568 circuit. But really, these cabs were large because they were of a “special design” that “greatly improves tone and volume without distortion, and permits optimum performance of the speakers.” At least that’s the reason according to the ’69 catalog.Also, another thing I’ve never seen before is a what appears to be a shipping tag of some sort (see photo).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.The boss came around and said what we'd be building. Probably the same as the pots and transformers that we just dug out of the boxes. Oddlings – Yet another printing error has surfaced, this time from the FEI (pre-CBS) days. Besides, no article in the Dating Fender Amps by Serial Number series would be complete without some interesting information, n’est ce pas?Although his job was somewhat limited, his recollections provided some really fascinating insights to how the amps were built.For instance, he confirmed our assumption that the amp chassis were put into stock after being stamped with serial numbers and that the chassis were pulled from the stock bins randomly (just as with Fender guitar neck plates).
Well, this universal “truth” was debunked when we found a bunch of amps with transformers made by the Better Coil and Transformers company.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.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.

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.
