Amp dating fender

In addition the datingbyserial number

Greg was passionate about Fender amps and his knowledge, insight and humor will be missed very much. First, the tables should be used as a guide only. The bottom line is to do your homework or enlist the aid of an expert. For the uniquely serialized models, the production estimates using my hypothesis, can be determined from the serial number tables.

The progress of this type of work is slow, hence the long hiatus, however, a lot of new data have been collected regarding Fender amplifiers, including production numbers. They actually held clipboards and stopwatches to measure how long it took for me to attach various parts.

But other changes may be meant to deceive. The following charts are the revised dating tables for Fender tube amps. The machine that stamped the serial number into the back of the chassis got stuck on number A and a lot of pieces were stamped with this number. Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.

These have not been observed or reported so the answer remains unknown. They were something to behold, all chatting away while soldering so quickly, it didn't hardly seem like they were looking at the amps. There is no way to separate out production for these models, but with enough data, we might be able to do some frequency distribution and such to determine a rough estimate. Greg kept his illness very private, even from this author.

As a result, there are a lot of amps out there that may look original, but are not. The amps that received the stamped suffix must also be added to this sub-total. It would have been very costly to destroy these units so two remedies were implemented.

The Australian Fender Distributor

Unfortunately, there is some sad news to report as well. For some reason, folks are willing to poke their head into tweed, blonde, brown and blackface amps, but not into silverface amps. Some caution is advised since it is likely that not all chassis were used due to defects or that duplicate serial numbers may have been stamped. These modifications are making this research more difficult for a couple of reasons.

In addition, the dating-by-serial number tables have been revised and are more accurate. The Australian Fender Distributor then installed V - V stepdown transformers in the bottom of the cabinets. Again, these are rare and exceptions to the norm. Advances have been made with regards to the production of tolex amps and it appears that much of this information can be applied to late s tweed amps as well.

The bad news is that there is still a lot of work that needs to be done on the silverface amps. Greg and I also disagree about determining production from serial numbers. One thing we know for sure is that production codes can help date an amp to a particular month within a given model run. Because the serial numbers are for a particular model and that chassis were stamped sequentially, is reasonable to assume that the serial number infers the Nth unit manufactured. But changes took place in as well.

Of course, this is all hypothetical, but still plausible. His passing is a great loss to this research team and the Fender amp aficionado community in general.
