Dating a fender amp bt serial number

26 Aug

In a BF Vibrolux Reverbs you could have either Jensen, CTS or Oxford, the BF Super Reverbs had Jensen, CTS, Oxford or sometimes JBL, the BF Pro Reverb had Jensen, Oxford or Utah, .In the silverface era Eminence, Oxford, Utah and Rola were more often used and Jensen was phased out.Our Buyer’s guide to vintage Fender amps explains in detail how you can date your amp by looking at serial numbers, tube charts, transformer codes, speaker codes, Fender logo, etc.

The resulting negatively-charged cloud of electrons is called a space charge.

Even at we struggle with keeping a correct amp and speaker model overview.

There are also exceptions to the rules where Fender delivered non-standard speakers in special orders, Christmas campaigns etc. See our Buyer’s guide to vintage Fender amps for a guide and picture gallery of the known original speakers in the blackface and silverface amps.

Some of the older Marshall amps have an inspection sticker on the top of the chassis which usually has the day, month and year the amp was actually made or inspected. Note, "A" Date Code ran for 18 months (July 1969 to December 1970) so the "B" date Code was never used and has been omitted. The serial number is generally located on the back of the chassis but from 79 to 80 it was on the front panel.

From 1969 to 1983 the date code was after the serial number.
