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.They were something to behold, all chatting away while soldering so quickly, it didn't hardly seem like they were looking at the amps.After that the foreman would add the tubes, turn 'em on and set the bias.” Export models – We’ve confirmed that Fender amps were distributed by Hagstrm in Sweden.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.
I have to wonder how often Fender used the SPEC check box and what features a “special” amp or cabinet would have?!
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).
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. The 5G12 Concert is the earliest version from very late 1959 and early 1960 so the existence of a tweed example, while extremely rare, is certainly plausible since Fender was making lots of tweed amps during the same time period.
Since the new owner would have likely removed this tag immediately upon arriving home, I’m amazed that the one in the photo has remained intact since mid-1968!
