6V6
The 6V6 is a beam-power tetrode vacuum tube. The first of this family of tubes to be introduced was the 6V6G by Kentucky Electrical Lamp Company, Ken-Rad Tube & Lamp Corporation in late 1936, with the availability by December of both Kentucky Electrical Lamp Company, Ken-Rad and Raytheon 6V6G tubes announced. It is still in use in audio applications, especially electric guitar amplifiers. Following the introduction in July 1936 of the 6L6, the potential of the scaled down version that became the 6V6 was soon realized. The lower-powered 6V6 was better suited for average home use, and became common in the audio output stages of "farmhouse" table-top radios, where power pentodes such as the 6F6 had previously been used. The 6V6 required less heater power and produced less distortion than the 6F6, while yielding higher output in both single-ended and Push-pull output, push-pull configurations. Although the 6V6 was originally designed especially for use in automobile radios, the clip-i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fender Champ
The Fender Champ was a guitar amplifier made by Fender. It was introduced in 1948 and discontinued in 1982. An updated version was introduced in 2006 as part of the "Vintage Modified" line. The Champ had the lowest power output and the simplest circuit of all Fender tube amps. The Champ had only one power tube, and the power stage circuit is, typically, single-ended and class A. Five watts and the simple toneful circuit allowed the Champ to be used easily and often in recording studios. Champion 800/600 First introduced in 1948, it sported the name "Champion 800" (with 8" speaker), changing a year later to "Champion 600" (6" speaker) with circuit designation 5B1. It was rated at about 3 watts, featuring a "T.V. Front" style cabinet; the 800 was covered in greenish fabric while the 600 featured two-tone blonde and brown vinyl covering. This style lasted until 1953, when Fender's cabinet style changed to the "Wide Panel" design with a tweed cloth covering. Fender also renamed ...

Beam-power
A beam tetrode, sometimes called a beam power tube, is a type of vacuum tube or thermionic valve that has two grids and forms the electron stream from the cathode into multiple partially collimated beams to produce a low potential space charge region between the anode and screen grid to return anode secondary emission electrons to the anode when the anode potential is less than that of the screen grid.Winfield G. Wagener, (May 1948"500-Mc. Transmitting Tetrode Design Considerations" ''Proceedings of the I.R.E.'', p. 612. Retrieved 10 June 2021 Beam tetrodes are usually used for power amplification, from audio frequency to radio frequency. The beam tetrode produces greater output power than a triode or pentode with the same anode supply voltage. The first beam tetrode marketed was the Marconi N40, introduced in 1935.Editors, (Feb. 1935"New Output Tetrode" ''Electronics'', vol. 8 no.2, p. 65. Retrieved 10 June 2021K. R.

Loctal Base
Tube sockets are electrical sockets into which vacuum tubes (electronic valves) can be plugged, holding them in place and providing terminals, which can be soldered into the circuit, for each of the pins. Sockets are designed to allow tubes to be inserted in only one orientation. They were used in most tube electronic equipment to allow easy removal and replacement. When tube equipment was common, retailers such as drug stores had vacuum tube testers, and sold replacement tubes. Some Nixie tubes were also designed to use sockets. Throughout the tube era, as technology developed, sometimes differently in different parts of the world, many tube bases and sockets came into use. Sockets are not universal; different tubes may fit mechanically into the same socket, though they may not work properly and possibly become damaged. Tube sockets were typically mounted in holes on a sheet metal chassis and wires or other components were hand soldered to lugs on the underside of the socket. ...

Vacuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fender Deluxe Reverb
The Fender Deluxe Reverb is a guitar amplifier made by the Fender Electric Instrument Company and its successors. It was first introduced in 1963 by incorporating an onboard spring reverb tank to the newly redesigned Fender Deluxe amplifier. Specifications The Deluxe Reverb is a 22-watt tube amplifier (at 8 ohms), powered by a pair ("duet") of 7408/6V6GT power tubes, one GZ34/5AR4 rectifier tube, four 7025/ 12AX7 tubes for preamplification and tremolo oscillation, and two 6201/ 12AT7 tubes driving the reverb and phase inverter circuits. Throughout its production, the amplifier has most often featured a Jensen C-12Q series 12-inch loudspeaker, although Oxford 12K5, Marlboro SE, Utah and Eminence speakers have also been used. The 22-watt output was obtained by operating the 6V6 power tubes well in excess of their maximum specified operating voltage. The amplifier weighs 42 pounds and measures 9.5" x 24.5" x 17.5". Variations The original Deluxe Reverb (circuits AA763, and later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fender Princeton Reverb
Fender Princeton Reverb The Fender Princeton Reverb is a guitar amplifier combo, essentially a Princeton with built-in reverb and vibrato. The 12 Watt Blackface version was introduced in 1964 and available until 1967; in 1968 it was changed to the Silverface version with a drip edge around the grill cloth. Amps produced after the end of 1969 saw a change in circuitry, the removal of the drip edge and a change in the rectifier from a 5AR4 to a 5U4GB along with a change in bias resistor value; a "boost" pull switch to the volume control pot was added in 1977. In 1980 and 1981 the Silverface version was cosmetically changed back to the Blackface. It was discontinued in 1981. Fender Princeton Reverb II This Paul Rivera-specified Fender guitar amplifier was introduced in 1982 to replace the Princeton Reverb. It was a completely different and significantly more powerful amplifier. Designed by Ed Jahns, it featured a built-in reverb, treble boost and mid boost controls, and a switchab ...

Standard Telephones And Cables
Standard Telephones and Cables Ltd (later STC plc) was a British manufacturer of telephone, telegraph, radio, telecommunications, and related equipment. During its history, STC invented and developed several groundbreaking new technologies including pulse-code modulation (PCM) and optical fibres. The company was founded in 1883 in London as International Western Electric by the Western Electric Company, shortly after Western Electric became the telephone equipment supplier for the American Telephone and Telegraph Company (AT&T) in the United States. In 1925, Western Electric divested itself of all foreign operations and sold International Western Electric to International Telephone and Telegraph (ITT), in part to thwart antitrust actions by the American government. In mid-1982, STC became an independent company and was listed on the London Stock Exchange; for a time it was a constituent of the FTSE 100 Index. It was bought by Nortel in 1991.
