What are Fender Utah speakers like
The site is nicely done and includes descriptions, pictures, and schematics for Fender tube amps as well as other Fendercentric information. And owing to the alleged year of the amp, it's likely that both speakers which are correctly identified are in fact replacements. What I'm saying is that pot and capacitory date codes are not a reliable indicator of guitar build dates. As the story goes, online dating and ghosting Leo Fender wanted Jensen to make some changes to speakers and either the speaker couldn't price constraints?

Again, I say let your ears be your guide. These codes don't make a lot of sense, so are noted below. Louis, Missouri for allowing me to photograph the speakers from his inventory. Also, the different component values could be due to a necessary substitution on the production line when a particular value was out of stock. Gibson used some pots with strange codes during the s that were confusing.
Because reconing wasn't a common option until the s, players simply replaced the speakers if they blew up. So, they widened the gaps to make them easier to throw together on a fast assembly line. And remember, even the dates indicated by the pots aren't that exact. How the Source-Date Code Works.
It would not be unheard of two different color speakers in the same year. In some cases, the speaker will sound even better. Another option is to install vintage style speakers. Of course, dating nine months the most foolproof way is to pull the chassis and look at the layout.
With all this information in mind, can you identify the following manufacturer and date of these source-date codes? And keep those blackface amp data coming! For those readers who may have joined us recently, getting number I am doing some Fender amp research along with Devin Riebe and Greg Huntington.
On less popular Fender instruments, such as LapSteels, pots can be as much as two years earlier than the actual date of the instrument. Actually, it's not a source code but is a manufacturers code for all National, Valco, Supro products. Well here's another classic post in quest to identify what kind of speakers I've got and when they were made. 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. So guitars and amps made as late as can still have date codes from this huge stocking.
The amps during this period could have the earliest style silverface grill cloth or the more familiar silverface grill cloth. Of course this all assumes the pot or speaker is original. The list, presented below, is based on our actual observations, but is not comprehensive. The decade, though not directly shown by the source-date code, speed dating cadiz was easily determined because this particular amp was only made during the s.

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. Utah went on to become Pyle of Radio Shack and car audio fame. Seems strange that they would both be Utahs from showing different colors. AlNiCo was the mainstay for decades because it produced a strong magnet which worked great in speakers. So, I have compiled a list of speakers used in Fender amps and took some photos of some of them as well.
However, the mystery will remain, how and why these speakers from got inside. Ran out of K ohm resistors? They had a Professional series, a Concert series, and a Standard series. This necessitates removing the chassis from the cab to change the voltage setting which would only be a problem if you hopping from country to country with the amp. The wire from the two K ohm bias resistors is connected to the brass control panel ground plate.
- If you can't, read the above information again!
- The actual power ratings have been published in several books so I'll discuss them in general terms here.
- Sometimes there just isn't enough information on electric instruments and amps to allow them to be properely dated.
Jensen speaker models denote their approximate power handling capacity and magnet type. Note the font style of the source-date code number always seems to be the same, for all speaker manufacturers. Also Ceramic magnets were cheaper to make than Alnico, hence their usage in the s instead of Alnico. Many amp geeks don't like Oxford speakers found in Fender amps from through the s. You have to make that call.
Today, reconing is a very popular option for players to keep their amp's speakers original. In most cases, the reconed speaker will sound nearly as good or as good as the original. Instead of a permanently magnetic magnet, electricity was used to make the magnetic field. There are some other codes used on Jensen speakers, as shown below. The higher the letter, the higher the power rating.
These mistakes were merely cosmetic. Both of them appear to be vintage. Many times a player can find an original speaker to replace the non-original speaker.
These amps do not have a bias trim pot. Although the cosmetics changed, the circuits remained unaltered from the blackface circuits on the earliest silverface amps. One clue that can be used is the ink stamped chassis date code that is usually located in the chassis, but is sometimes found on the underside of the chassis behind the tubes. Usually this isn't too difficult.

Leo Fender was notorious for tweaking circuits and the results of some of his tinkering can be found on late examples of an amp prior to the switch to a new circuit. Interestingly, these amps have Triad power transformers while concurrently produced domestic models had Schumacher units. 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. What are some of the numbers that are on the transformers.
The Q and P suffixes denote a medium power rating. This supply lasted for over five years. Also, the amp eats power tubes, does not have much headroom and breaks up early.
Another code, C, is printed on the speaker as well. The author and his partners would like to thank those people who have sent us Fender amp information and you know who you are dahlings. They are were often sold as replacements for blown speakers which is probably one reason why the ended up in more than a few Fenders. Often the differences are minor such as small changes in resistor or capacitor values. In either case, the code works the same.
- It's more then likely that one of the speakers blew within a few months of the amp being purchased or one blew years later and someone found a very close replacement.
- Are the wires of the right era cloth insulation for older stuff?
- The companies also needed to produce speakers with long term reliability, so they doped the surrounds.
- The source-date code found on pots and speakers gives the manufacturer and date roughly when the components were made.
It's no wonder that watt Twins easily shredded a pair of them. Our research efforts are now in their fourth year will it ever end? As you have probably noticed, there is plenty of information here to help date the brands that I am interested in.
There is a strong market for used speakers. It's worth mentioning since a lot of people rely on pot dates. Of course, I have no way to verify the assertion. The prefix code letter identifies the type of magnet used in the speaker.
That could explain why they sound good. But where does that leave everyone else? Then from and later you see Fender using speakers from all the above mentioned makers. Either way, the speakers sound great.
This seems silly, as we're talking about electronic parts not eggs. They both look the same construction wise. If so, you can check the pot or speaker for the source-date code, and determine an approximate age from that.
