A Bill Haley Stereo LP was released in April , it’s sales must have been almost zero, but copies are around as likely sold off as clearance. By the amount of these styles in Stereo by clearly very few sold, even in Beatles ‘Sgt Pepper’ huge seller is more common in Mono. The idea these Stereo Amps mainly were just quick cash-ins is noted in the books of the time, as with any the next generation will have been superior in quality like the Mono ones were considered. This clearly is one of the prime Valve amps, though there are 25w w on this page that will outdo this one. We’re not likely to try one so to have a look now we have somewhere to type it is worthy. Underneath neatly wired if a “is that all there is” to the design compared to others. Quad IIs get this a lot.

How can I find out how old my amplifier is? While dating Fender amps made before by serial number is all but impossible as records of these numbers were never kept , all hope is not lost—the charts below should prove helpful in dating your Fender amp. First, it will be useful to you to understand the following five terms in order to choose the correct chart for dating your amp: Silverface, Blackface and Brownface are slang terms used to identify Fender amplifiers based on the color of the control panel these terms are often misconstrued to refer to the color of the grille cloth.
17th of July , Bo Johansson made a very nice uTracer with the thumbwheel switch from a scrapped AVO MKIII! Dear Roland, It was a while ago I bought the uTracer kit from you!
I promise the tables will still be there after you finish reading. We also received a report of a tweed 5G12 Concert. The 5G12 Concert is the earliest version from very late and early so the existence of a tweed example, while extremely rare, is certainly plausible since Fender was making lots of tweed amps during the same time period. Working at FMI — I was able to interview a fellow who wishes to remain anonymous who worked at Fender in in the amp department. Although his job was somewhat limited, his recollections provided some really fascinating insights to how the amps were built.
For instance, he confirmed our assumption that the amp chassis were put into stock after being stamped with serial numbers and that the chassis were pulled from the stock bins randomly just as with Fender guitar neck plates. The boss came around and said what we’d be building.
How can I find out how old my amplifier is?
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?

Both uTracers PCB are okay. The wireless connection from my notebook to uTracer operates with BlueTooth and so I have more space in my motion. If the measure procedure lasts longer report the GUI a timeout signal from uTracer. The uTracer arrived safely yesterday and I verified the I will proceed to build with that in mind and not place the incorrect resistors. I look forward to completing the build and putting the uTracer to good use.
I will send pictures of the build as I progress and of the completed project. I plan on making my finished uTracer look like an antique ‘s Leeds and Northrup type design made with a wood frame and black panels.

The first Fender solidbody model, the Esquire , lasted in name only from June to October This model name was replaced by the “Broadcaster”, which lasted in name only from the October to January All Broadcasters have truss rods, where many Esquires often have no truss rod. In Gretsch had trademarked the name “BroadKaster” for a line of drums.
Tube vs transistor amps. If you’re struggling with discovering a sweet tone, it’s time you get yourself a proper Fender tube amp. It doesn’t have to be a vintage amp, but is has to be a tube amp.
Hello Ronald and friends! It is very nice to write You for a very long time. And thanks for the very well working uTracer. So here they come, hopefully You mail does not fill. You can see from pictures, that I have not made the other raw of banana plugs down. When it comes two or more connections to same plug, I just put them together to same banana point. It has worked so far and I have not seen any oscillation or so.
The V parts are still waiting in the box some good day, job is small, but beginning is big.
In electronics, a vacuum tube U. For most purposes, the vacuum tube has been replaced by the much smaller and less expensive transistor, either as a discrete device or in an integrated circuit. However, tubes are still used in several specialized applications such as guitar amplifiers also called a valve amp outside the U.
“Still purrs, like it was yesterday.” — Batman tanking out the Bat Tank in Batman: The Dark Knight Returns after ten years. There is a certain degree of Truth in Television involved in this trope. Often the newer and more “advanced” a technology is the more points of failure it can have. Older.

Yes, the latter isn’t as precise of a method, however, it doesn’t rely on complicated electronics which can malfunction, be jammed, run out of power, etc. As long as it is not a cloudy night a knowledgable mariner can easily get to where he needs to go.
The Absolute Sound magazine http: In particular, they have become known as one of the premier manufacturers of single ended amplifiers SETs , preamplifiers. The soundstage at the show demo was just huge with holographic images dancing within a truly holographic 3d soundstage. Those big monoblocks also delivered the delicacy and midrange glory that SET is famous for but with a big tight bass wallop and crystal clear extended highs for which SETs were not known for at all…..
Introduction. 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.
This results in a fatter tone. Signal distortion In signal theory distortion is defined as a change of amplitude, frequency or phase. These are just different words for distortion. Distortion is for many tube amp guys considered a good thing since it makes the tone thicker, fuller and with more sustain. This is not desirable for all instruments. Will distort if signal level is very high hot humbuckers, boost effect pedals.
Signal enters the EQ stage with treble and bass pots. Signal enters the volume potmeter. Volume pot is not amplifying anything, just letting more current through. Will distort if signal level at this point is high, as a result of all previous signal processing to the original input signal. The cathode caps and resitors in preamp tube circtuits will add sag and compression if tube is pushed hard.
The signal in the reverb path is heavily amplified by the reverb driver tube V2 both halfs which drives the reverb tank like a loudspeaker.
The progress of this type of work is slow, hence the long hiatus, however, a lot of new data have been collected regarding Fender amplifiers, including production numbers. Advances have been made with regards to the production of tolex amps and it appears that much of this information can be applied to late s tweed amps as well. In addition, the dating-by-serial number tables have been revised and are more accurate.
The bad news is that there is still a lot of work that needs to be done on the silverface amps.

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.

The Super Reverb can be really loud and even interfer with the bass guitar. Just two speakers are enabled 4 ohms with a 65 Super Reverb having tremolo disconnect mod and V1 tube pulled out. These tubes have different frequency responses than 12AX7, particurlarly when distorting. People describe these tubes to have less harsh and buzzy distortion. This mod does not alter the tone significantly when amp is played clean or when only the power amp section distorts.
It is so easy to enable and disable that it can hardly be called a mod. This is the preamp tube for the normal channel which you are not using when playing the Vibrato channel. This mod is safe. It has stood the test of time and been been done by players in 50 years in blackface Fender amps. Very practical mod at practice and low volume environments.
If you pulled the V1 12AX7 tube you may use it as V6 phase inverter.

Features one channel and two inputs; volume, bright, treble, treble expander, bass, bass expander, bright switch, deep switch, stand-by switch, pilot light for stand-by and operate. This amp was built to play larger halls and outdoor concerts. The lack of reverb was not a big issue as most live performances had acoustics full of reverberation halls, arenas.
Peter Traynor built these things to stand up to road abuse, unlike a lot of vintage stuff. It sounds great with either bass and guitar, providing a clean and loud tone.
Details of the various Traynor amp models, and opinions about them.
The purpose of this guide is to help you recognize a good Fender amp by reading about it and looking at pictures. It will allow you to make safer purchases on a global market without having to physically play an amp before acquiring one. There are many facts to consider when determining the condition and originality of a vintage amp. While the collectors are primarily interested in originality, the musicians see the amp as an instrument.
This will affect the priorities and decision making in a purchase. If your plan is to play and gig with your amp you should focus on tone and robustness. To pay our respect to Leo Fender we must all try to conserve the vintage Fender amps on this planet. We should all strive to keep these amps as original as possible.
