Dating cts speakers
Many tens of thousands of products were manufactured by the various DeArmond companies over more than four decades. In order to verify the date of manufacture for guarantee purposes, some products had their production date month, day and year rubber-stamped or handwritten internally during manufacture.
The rubber-stamped items included FH pickups and effects pedals. Some FH pickups had the last two digits of the year of manufacture stamped on the small metal tab normally covered by a black plastic sleeve. The Company name was also stamped on the underside of some products and while not as accurate as a precise date, this at least establishes a period.

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”.
The source-date code found on pots and speakers gives the manufacturer and date roughly when the components were made. It may have been some time before the part was installed at the factory, but it still provides a good approximation of when the gear was made. The source-date code will signify the earliest possible date that the instrument or amp could have been made. This isn’t going to be exact, but it will give you a “ball-park” age.
And remember, even the dates indicated by the pots aren’t that exact. For example, if you buy a brand new CTS pot today, they are dated a month or two in advance! It’s worth mentioning since a lot of people rely on pot dates. That said, it’s not uncommon for pot manufacturers to post date pots anywhere from a few weeks to as much as 18 months.

Possible culprits include the preamp tubes, the power tubes, the hum balance resistors, and the power supply caps. Thanks for your input. I have a Deluxe Reverb and am trying to figure out if it has a Utah or some other kind of speaker.
I’m looking at a 2×15 cabinet to buy with CTS speakers in them, the seller can’t find a serial number on the cabinet, but, the serial numbers on.
The Code on the tube chart of your Fender Amp is made up of two letters. The First letter equates to the Year and the Second letter to the Month. Reissue amps also use stamped Date Codes. Examples of “Hand Stamped” Date Codes. 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.

There has always been a considerable interest in the serial codes, options and the history of the true original Heritage series Klipschorn, LaScala, Belle, Cornwall and Heresy. The original “Codex” was published on the Forum several years ago, but times have changed, and with the Klipsch transition to the new forum, it appears that the document is either “lost”, or deleted, etc.

I know, I know. For those readers who may have joined us recently, I am doing some Fender amp research along with Devin Riebe and Greg Huntington. Our research efforts are now in their fourth year will it ever end? Again, I would like to thank everyone who responded to our request for data as outlined in Parts 1 and 2. Early silver face amps: Part 2 went into this topic in some detail, but since that article was printed, I have been asked a lot of questions about this subject.
Part of the confusion stems from the lack of any AB or AC tube charts. Fender never printed any since there were plenty of leftover AB tube charts available and these were used well into

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.

Find the source code stamp, which is a series of six or seven numbers, that will be stamped on the speaker. The stamp can be found on any part of the speaker, but it will be readily visible no matter the location. Write out the source code and divide it into three sections. The first three numbers represent the company that made the speaker, the fourth and fifth if there are seven numbers represent the year the part was made, and the last two numbers represent the week that the part was made during that year.

Guitar Identification Guide. Bass Identification Guide. Properly identifying Carvin guitar amplifiers can be much trickier than identifying Carvin guitars and basses. For starters, there is no serial number information currently available, from this site, or from Carvin directly. So, unfortunately, having a serial number is of no benefit in identifying the year of a particular amp.
The best one can hope for is to narrow down a particular model to a range of years – but finding a specific year of a particular amp is just about impossible to do. However, there are quite a few features that at least make it easy to narrow down an amplifier to a range of years. As with other Carvin gear, the first, and most obvious, detail to look at is the logo on the amp itself. The earliest Carvin amps had the same logo as was found on guitars, basses and other instruments, shown at left.
