The source-date code on a pot is a 6 or 7 digit code impressed into the casing of the potentiometer. For speakers this code can be 5, 6, 7 or 8 digits long, and it’s ink-stamped or paint-stamped on the “bell housing” of the speaker. In either case, the code works the same. The first 3 digits on a pot, or the first 2, 3 or 4 digits on a speaker are the source or manufacturer code. The remaining 3 or 4 digits are the date code. In 3 digit dates code, the 1st digit is the last digit of the year. On 4 digits date codes, the 1st and 2nd digits are the last two digits of the year. In either case, the remaining 2 digits are the week of manufacture 01 to With this in mind, remember if the last two digits of the source-date code are greater than 52, you’re not looking at the source-date code! Also it’s worth mentioning:

A true holy grail instrument in every sense, this SG combines the inherent warmth and power of a solid mahogany body with the attack and articulation of an ebony fretboard for an ideal tonal pairing. The guitar is dynamic and soulful, and when you strike a chord the entire instrument responds with a lively spank and rumble. The results are astounding, with incredible bark and sweet, glassy articulation in the down position, contrasting with a thick, throaty howl when all the humbuckers are engaged.
The guitar weighs in at 7lbs 14oz and balances well on a strap.
CENTRALAB POTS lot of 4. 1 MEG SOLID SHAFT GUITAR POTS. FENDER GIBSON. Dating to around Height inches. Body diameter inches. Condition. The decanter is unstained. The only fault is some nibbling to the inside of the rim where the stopper fits through use. The stopper is fine.
These early receivers have a PW-D micrometer dial that has a bluish-gray Index dial and an inner Number dial that is red with white numerals. The matching loudspeaker is the early style cabinet with a 10″ Rola K electrodynamic speaker only available for the production. History of the Design and Production Many radio engineers of the thirties firmly believed that the absolute best sensitivity and stability of a communication receiver’s RF amplifier, First Detector and Local Oscillator could only be achieved by using “plug-in” coils.
This type of approach eliminated problems of lead length, shielding and stability along with isolation of unused tuned circuits – problems that were commonly found in broadcast receivers using conventional rotary bandswitches. Plug-in coils were a hassle, no doubt. James Millen, National Co. But, how to effectively eliminate the valid arguments against plug-in coil use in a new product? Certainly, National was having fabulous success with the HRO receiver, which had been in production since early

This list is circa , and some codes have been reassigned or added since that time. 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.
They generally follow the following format:
The SD-9 with two circuit boards (one is down with the pots) has less oscillation problems when you turn it up high, so I prefer modifying those types. Also the Maxon has .
Wah Wah Mods The mods on this page are primarily concerned with the Dunlop Crybaby and Vox V wahs, but they can be applied to most wahs which have an inductor. Mods to PCB These mods are all fairly cheap to do and they’re reversible, so it’s not the end of the world if you don’t like the results. Refer to the photos below if you’re not sure which parts to change. This gives a more vocal quality to the wah.
Gain and Bass Response Replace the ohm resistor some have or at the emitter of Q1 with a lower value. This increases gain, which is useful if you’ve converted to true bypass. The bass response is also increased. Too low a value here may introduce some distortion and make the wah sound muddy. Try – ohms to start with. Midrange Replace the 1K5 resistor between the base of Q1 and the inductor with a larger value.
This increases the midrange and helps if your wah sounds dull and muted when you rock the pedal back.

Strings load through body. I seriously doubt the 1. The pickup has round knurled height adjustments. Post-war instruments had Phillips-head screw height adjustments. The edges of the magnet appear sharply squared off.
The author Note: The RMC pots are now available with a special taper just like the Clyde’s ICAR that makes any wah sound ‘s interesting that the Stereo Fuzz Wah didn’t use the TDK inductor and used the original caps.
Return to the Main Index. Sometimes there just isn’t enough information on electric instruments and amps to allow them to be properely dated. And many people ask me to try and determine the year of their old amplifier, or to help them with the year of their older off-brand electric guitar. Since I primarily collect amps by Fender, and guitars by Gibson, Fender, Martin, National, Epiphone, Gretsch and Rickenbacker, I really can’t help them with these other less popular brands.
As you have probably noticed, there is plenty of information here to help date the brands that I am interested in. But where does that leave everyone else? Well I’m not one to leave you out in the informational cold, so here’s something that I use quite often in dating amplifiers and electric guitars. It’s called the “source-date code”, and it can help determine the approximate age of an electric instrument by the date its components were manufactured.
Source-Date Codes On American made vintage gear, the pots and speakers provide an excellent opportunity to date a piece of equipment by referencing their “source-date code”.

Congrats on a really nice looking console. Static crashes have been so bad here I have had problems hearing you guys. I bought “used” mixer components off of eBay and cobbled them together. The main mixer guts came from a Shure Prologue mike mixer, the equalization came from a Samson Mixpad 6 mixer, the cue amp I built from a kit, the phantom voltage came from a junker Nady power supply. The pots with cue switch, switches, red lamp, tie strips, relays all came from Allelectronics.
The electronic is alloriginal and untouched with two Centralab pots stamped dating them to 12th week of , the original pickup has an output of 10,86K, the neckstamp reads 5 APR 65 C. The neck is a medium-sized C-profile and very comfortable to play.
E-H talking pedal I just earlier this evening found out that what I thought was a talking pedal was actually called a Golden Throat. What does a talking pedal do, and how does it work? Is it the same thing as a Golden Throat? They are completely different. The golden throat is a “talk box” like Frampton, Walsh, etc used. It is a speaker driver connected to a tube which goes in your mouth and needs to be miked through a PA to be used. Your mouth acts as a filter. The Talking pedal is like a big wah wah pedal, but instead of saying “WAH” it says “eee aaaa iiii oooo uuuu” when it is moved, the vowel sounds.
It goes in the path between the guitar and amp, much more useable than a talk box. But the talk box can make more different sounds. In the Bad Stone I can’t switch back and forth from auto to manual.
Seattle, Washington, Ships to: Finished in original Cherry nitro lacquer with nickel hardware and hailing from what is arguably the most celebrated production year for any SG model, this guitar is utterly unique and as Vintage Guitar Magazine succinctly puts it, “the number of non-white SG Customs that have surfaced over the past 50 years could be counted on the fingers of one hand. The guitar is dynamic and soulful, and when you strike a chord the entire instrument responds with a lively spank and rumble.
