Not only that, but to meet Swedish safety codes, Hagstrm removed the external voltage selector switch (fitted to all blackface and silverface export models) and hardwired it internally (see photos).
Notice that the original Fender back panel was removed and replaced with a Hagstrm panel.
I remember two 'suits' from upstairs standing behind me occasionally doing time studies.
They actually held clipboards and stopwatches to measure how long it took for me to attach various parts.
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.
One thing we know for sure is that production codes can help date an amp to a particular month within a given model run.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).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).I think in the corners of the boxes were older pots remaining from earlier dates... Like I said, there were 5 or 6 of us at the benches every day.
