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.Early silver face amps: Part 2 went into this topic in some detail, but since that article was printed, I have been asked a of questions about this subject.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.Again, I would like to thank everyone who responded to our request for data as outlined in Parts 1 and 2.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.There still seems to be some confusion about how to distinguish between a silverface Fender amp that has the desirable AB763 circuit and one that has the less-desirable AB568/AC568 circuit.Part of the confusion stems from the lack of any AB568 or AC568 tube charts.
Devin runs Doc's Music in Springfield, Missouri and his interest lies in the woodie and tweed Fender amps made from 1946 through 1960.
Fender never printed any since there were plenty of leftover AB763 tube charts available and these were used well into 1969.
Although the cosmetics changed, the circuits remained unaltered from the blackface circuits on the earliest silverface amps.
It would be more accurate to say that approx 650 of each of these models were produced in ’60.
