Dating fender amps silverface

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).These are marked with EIA code “831” and are most prevalent during the 1966-68 time period.Some examples include a '66 Princeton Reverb and ’66 Pro Reverb with Better Coil output transformer, a ‘66 Deluxe Reverb and ‘67 Twin Reverb with Better Coil reverb transformer, and a 1968 Vibro Champ with Better Coil trannies.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).

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.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.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.
