Dating guitar amps
Silly me , I just published a link on how to date your Fender amp and I just went and dated y Deluxe Reverb ! It sounds great and so I have decided not to mess with what was a factory Mistake/ Change/ Customisation? This one is an odd amplifier because when I decided to start on the restoraton, I noted that the circuitry was not pure Silverface but a blend of Blackface and Silverface.Note that each different period is approximately during each different ownership. Pre 1953 - These amps can only be dated by the EIA (Electronics Industries Association) codes on the speakers and other parts. This was a six-digit number like this: YMMNNN, which was the last digit of the year, month, and number of production.
It was only fitting to introduce a third serialization system.
Non-Schumacher transformers – It’s been universally accepted that Fender only used Schumacher transformers on amps made in the 1960s and 1970s.
These are marked with EIA code “606” which is the company number for Schumacher.
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.
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.
