We used these in Master Control and two production control rooms and when I heard them, it was love at first sight. The has been mostly superseded by newer models in recording studios, but is still used in broadcast facilities even after 30 years. I run a tube system with a full analog chain vinyl to tube preamp to tube amp so I selected the for its modest 45hz bass rolloff into hz. I had tried a couple of different off the shelf Polk units in the 10 inch range but found them to be much to warbly down in the nether regions. But when i plugged these babies up, I realized that mama was home. The coil does become very active unless the enclosure is properly isolated, so be careful going above 5 watts with your contour control activated. The midrange is driven with a 5 inch, 1. Personally the mid is a bit dull between and hz, but that is where the EQ circuit comes in, which is described below. The high end driver is simply amazing. The voice coil is.

Its origins are uncertain: Ogham is also known as or ogham craobh tree ogham beth luis fearn or beth luis nion, after the first few letters. Ogham probably pre-dates the earliest inscriptions – some scholars believe it dates back to the 1st century AD – as the language used shows pre-4th century elements. It is thought to have been modelled on or inspired by the Roman, Greek or Runic scripts.

December Learn how and when to remove this template message Thomson had heart problems and nearly died when he was 9 years old. He attended the Royal Belfast Academical Institution , where his father was a professor in the university department, before beginning study at Glasgow University in at the age of 10, not out of any precociousness; the University provided many of the facilities of an elementary school for able pupils, and this was a typical starting age.
In school, Thomson showed a keen interest in the classics along with his natural interest in the sciences. Throughout his life, he would work on the problems raised in the essay as a coping strategy during times of personal stress. On the title page of this essay Thomson wrote the following lines from Alexander Pope ‘s Essay on Man. These lines inspired Thomson to understand the natural world using the power and method of science: Unsurprisingly, Fourier’s work had been attacked by domestic mathematicians, Philip Kelland authoring a critical book.
The book motivated Thomson to write his first published scientific paper  under the pseudonym P.

The Celestion register of speaker types – the “T” book – is printed in extenso insofar as it relates to 12″ speakers by Michael Doyle, “The History of Marshall” , appendix 1, pp. Info has also been usefully assembled on the Bygone Tones site. There seem to be three basic types 1 small nuts on the cap, date code stamped on frame; 2 small nuts on cap, date code on gasket; 3 large screws on cap, date code on gasket.

Permalink. It would appear to be around ~early but then again, the Vibro-Kings were one of the amps that flew under the radar, and s/n dating for these amps are a guess at best.
Some of the test and monitoring equipment for the military was the best that could be produced at the time and no expense was spared in its construction. At the budget-built end, there were the countless test-gadgets intended for radio repairmen or radio hobbyists that might seem to barely be able to perform the intended task but clever designs sometimes resulted in very useful test instruments. Biddle of Philadelphia imported these instruments and each box has his tag attached.
Biddle was also a very early major builder and supplier of wireless equipment with Reginald Fessenden being one of his prominent customers over a long period of time. At the turn of the last century, many precision measurements had to be calculated because the measurement couldn’t be made directly since many of the instruments we take for granted today hadn’t been developed. A known precision resistance allowed one part of the equation to be selected and the remainder was then calculated.
These types of boxes were used in DC Resistance bridge circuits for precise measurements of an unknown resistance Wheatstone Bridge circuits or in other circuits for calculating current flow, low voltage levels or comparison evaluations. Many experiments were carried out at Mt. Wilson and the facility there had has a lot of very early test gear. I was given these boxes by my old Virginia City friend, Maynard Clark who worked at Mount Wilson Observatory Maynard designed much of the computer software for the various telescope drive systems at Mt.
Biddle Company – “JAGABI” Adjustable Slide Rheostat-Potentiometer These large, adjustable wire-wound rheostat-potentiometers were generally used in college and university physics laboratories when performing experiments in electricity where fairly large currents were involved. Most of these types of devices used nickel-chromium wire wound on ceramic forms.

Dating Vintage Guitars and Amps by Source-Date Code. 03/02/ Return to the Feature Index. Return to the Main Index. 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.
It has half the number of power tubes, smaller transformers and a tube rectifier in stead of diodes. Together this makes the Pro Reverb break up significantly around the usual volume level 4, while the Twin Reverb is clean almost all the way up. The power transformer and power tube circuitry is equal to the Super Reverb, but a smaller output transformer lowers the clean headroom and introduces sag and breakup.
For many years it has been a relatively unknown amp. In the blackface and silverface years players wanted powerful amps, and the Pro Reverb was probably considered too weak. In modern times where low wattage breakup has become desirable, the Pro Reverb has become very popular. Different speakers may alter the tone significantly in the Pro Reverb, as in all amps. A set of Celestions give you a Britsh Marshall color with strong mids, while traditional Jensen-style speakers give you the classic Fender tone.
Speakers are very difficult to recommend since the tone experience is nothing but personal taste.

Descriptions include “the sacred sound, the Yes! The Chandogya Upanishad is one of the oldest Upanishads of Hinduism. It opens with the recommendation that “let a man meditate on Om”. It is the symbol of awe, of reverence, of threefold knowledge because Adhvaryu invokes it, the Hotr recites it, and Udgatr sings it. Their conversation evolves to a discussion of the nature of man, knowledge, Atman Soul, Self and moksha liberation.
The wire from the two K ohm bias resistors is connected to the brass control panel ground plate. The only thing connected to the bias cap/diode is the tremolo circuit. The cathodes are tied together and connected to a single ohm resistor and 80 mfd V bypass capacitor which are .
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 Although the cosmetics changed, the circuits remained unaltered from the blackface circuits on the earliest silverface amps. The date of the change from the blackface circuit to the CBS silverface circuit was dependent on the model, but most of the amps that were modified received the circuit change by mid-year of The cosmetics of the silverface amps during the transition between circuits was also in transition making it difficult to determine circuit type on cosmetics alone.

Do you need sex without any obligations? Choosing Replacement Speakers There are a LOT of different types of speakers to choose from; how can you possibly make the right decision? We can simplify the task by narrowing down the choices for back box speakers and cabinet speakers.

The Weber 12F was the proper choice because I wanted to “open up” the sound and have more headroom overall and clarity. I did have to build a new speaker board (baffle), which I did from baltic birch plywood since PRs have a 10″ speaker.
I was contacted by a G player in the States and a G player in Norway both using the first run, early “prerelease” version of the guitar electronics. The cards are labeled as version “A. You can also see jumper wires soldered across the board. The first time I tried to repair a failed op-amp in a G , I realized that the pin-out documentation was wrong on the schematic. The pin out information was correct on the G Service Manual Schematics schematic, which uses almost the same circuits.
All the G s and G s that I have checked have op-amp pin outs consistent with the G These op-amps are the top three op-amps in line with the pin ribbon connector. This is consistent with the G schematic. The line-level amplifiers are surrounded by resistors for a simple gain circuit, and the hex fuzz amplifiers have the network of diodes used to create the fuzz sound. From looking at the version “A” photo, it appears the one op-amp is used per string to both amplify the signal and create the hex fuzz sound.
If you look at IC6, at the top of the version “B” and “C” card, you can see resistors just to the left of the chip creating gain in the negative feedback loop, and additional diodes just to the right side of the chip for generating fuzz.
