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). I promise the tables will still be there after you finish reading. Okay, I know you’re all just dying to skip ahead to the serial number tables but try to contain your excitement and read through the article first.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).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.
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.Mid-1968 Super Reverb export model modified by Hagstrm for the Swedish market.Note the removal of the voltage selector switch and hard-wiring. I just discovered that the silverface Bandmaster speaker cabinet (the big, tall one without tilt-back legs) is ported (see photo). I guess this is what the 1969 catalog refers to as “large, individual specially designed baffles.” And all along I thought the big n’ tall silverface cabs were just a macho thing to compete against the awesome looks of a Marshall half stack or full stack.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.
