Potentiometer code dating - 2006 dating in love new site zealand

My discussed pot in this thread is R137yyww = R1378131 = 1981/31st week (R137 = mfg)Typically, before 1981, you will see "wwyd" = week/year/day of week Example on a 1970s Stratocaster neck butt date "0903-2455" 09=Stratocaster 03=Maple Neck 24=24th Week 5=1975 5=Friday What I've been understanding, serial numbers are only an indication of a year, but could be five years off, like my Telecaster. I know nothing about the Lipstick pickups🤔 Heard of them and recently saw a Tele with a Lipstick on the neck pickup 🤔 Kevin, my thing is this.

The first string of numbers is usually the part number, or sometimes the pot value.

This sounds perhaps a little silly since the shelf life of tubes is decades, at least (indefinite in practical terms), but some OEM's might have beenn a bit irritated by occasional consumer complaints such as "my 1961 model TV has 1959 model tubes in it!

" Tubes made for the US military, or certain OEMs (such as some test equipment manufacturers) that requested it, continued to carry numerical date codes.

So a pot stamped 1377833 is a CTS pot made in the 33rd week of 1978.

Note that this does not mean a Muff with a 1978 pot was actually made in 1978, it just means it was not made much earlier than 1978.

When I replace pick ups I put a new set of pots on it. I do an install that is cleaner than the ones that came new on the guitar.

If they need replaced just do it they are about .00 each.In years past, EIA (Electronic Industries Association) also went by the name of RETMA, and the original acronym of RMA (Radio Manufacturer's Association).Dating Telecaster Pot Potentiometer, Please Help Hi! Toppscore Well, if anyone knows how to date a Telecaster pot, PLMK. I also did not know you could date a guitar by them. Fender is/was very consistant as how the week/year dates were labeled/stamped on most vendor supplied items used within Fender guitars & amplifiers.Code formats were not completely standardized, but a little deciphering will generally yield the info of interest.Note that many makers also stamped OEM (Original Eqipment Manufacturer) part numbers above or below the EIA code, in some cases parts makers or the customer elected not to include the EIA codes, so not all parts have them.Then, the neck-butt date code stamp gives the Strat/Tele a true year & week of production. There are alot of people like me that up grade or just fix stuff.
