Dating vintage fender amps serial number dating no reply
Here is a cool link to a Vintage Fender Amp price history chart that tracks sales data for specific amp models by the month.
Date Code: Wide panel, narrow panel, brown, blonde, and black face amps have a date code hand-stamped on the tube chart. The first letter translates to the year and the second to the month. Example: FG=July 1956, QA=January 1967, and a reissue CG=July 1992 EIA Source-Date Codes: Electronic components such as transformers, potentiometers, speakers, and some capacitors are often stampted with a date code indicating who manufactured them and when.
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.
If possible, open up the chassis and check a few of the pots’ and capacitors’ manufacturer codes.
Remember, many components could have been changed over the years, speakers blow, caps dry out, transformers melt down, and pots wear out.
Okay, I know you’re all just dying to skip ahead to the serial number tables but try to contain your excitement and read through the article first.
(see chart below) YY = is a one or two digit code indicating the year.
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.
These units look, and apparently sound, just like the Schumacher-made units so it’s easy to overlook that “831” code.
There are several ways to determine when a Fender amp was produced.
First use the cosmetic features to get a range of possible years.
