Dating fender guitar pots
Serial Number: There is no information readily available for dating Fender amps by serial number but there are people working on it. Circuit Code: In 1963 Fender stoped using model numbers to identify schematics and began using the model name and an assigned circuit number.These circuit numbers which are located on the tube chart can be usefull for getting a rough date on an amp.in 1947 Gibson changed the serial number pattern and in 1954 went from white labels to orange labels.Since all the instruments using this serial number pattern were acoustic or semi-hollow the labels were located inside the instrument body.The inscription on this one is B-500K and it looks old Any help will be appreciated... Better pics of the other sides of the pots would help.Yes the first two are '99 dates, and the B-500k is a 500k linear pot (could be original if it's one of the volume pots, is that the only thing it says on the pot? And the WD - labeled pot is probably a replacement from WD, maybe CTS or CGE, can't tell from the pics.Remember, your amp is newer than the newest component.So if you find pots from late 68 and transformers from early 69 you can be pretty sure your amp is a 1969.
Remember, many components could have been changed over the years, speakers blow, caps dry out, transformers melt down, and pots wear out.
The first digit is the year and the other numbers are production numbers.
This system is fairly reliable for guitars made from 1953 to 1961.
The inscription on this one is B-500K and it looks old Any help will be appreciated... Some of them are possibly original to the MM I bought recently (see this thread: The inscription on this one is also EP085 250K 9904 The inscription on this one is 08 WD 500 or DB WD 500.
t=173223) The inscription on this one is EP085 250K 9904. It's a bit corroded and it's difficult to judge its age... I think the "EP" on the two pots means they are CTS, at least I think that's a designation for CTS pots.
