Dating fender amplifier serial updating downlevel os configuration
Since several models can share one chassis type (for example, the early brown 5G7 Bandmaster, 5G5 Pro and 5G12 Concert), this kind of interpretation is inaccurate.
Instead, there were approximately 2000 of these chasses produced, which then ended up as one of the three models in question.
Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.
and these changes are often disclosed and of a non-malicious nature.
It would be more accurate to say that approx 650 of each of these models were produced in ’60.
It’s been over a year since Part 2 of this series was printed, but that’s because I’ve been busy collecting data.
The main focus of this article will be speakers found in Fender amps, but before we get into that topic let’s go over a few other areas first.
Other things to look for include chasses placed in cabinets from a different year, “doctored” tube charts, non-original control plates (usually reproductions) on silverface amps, original transformer bell ends (they have correct date codes, of course) on non-original transformers, and non-original knobs (either repro or silverface knobs on blackface amps).unusual things can be found such as the empty “Pulse Adjust” hole on the rear of early ’60 brown amps, the “middle” volume control, use of tweed style grill cloth, strange non-documented transitional circuits, and changes in tolex color including the super-rare cream colored “brown” tolex that is found on some late ’60 amps. Given that people may refer to this information seeking specific production quantities of amps they are curious about, it should be pointed out that the serial numbers apply to chassis types, and not specifically to amplifier models.
Looking at serial numbers next to the ’60 5G5 brown Pro Amp for example, we see numbers ranging from 00001 to 02000, suggesting that there are 2000 of these amplifiers made in ’60.
Part of the confusion stems from the lack of any AB568 or AC568 tube charts.
For those readers who may have joined us recently, I am doing some Fender amp research along with Devin Riebe and Greg Huntington.
Our research efforts are now in their fourth year (will it ever end? Part 1 and Part 2 of this series can be found in the March 1997 and November 1997 issues of TCG, respectively.
