Acoustic Guitar Amplifier
A guitar amplifier (or amp) is an electronic device or system that strengthens the electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a ''combo'' amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight practice amplifiers with a single 6-inch speaker and a 10-watt amp to heavy combo amps with four 10-inch or four 12-inch speakers and a 100-watt amplifier, which are loud enough to use in a nightclub or bar performance. Guitar amplifiers can also modify an instrument's tone by emphasizing or de-emphasizing certain fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leatherette
Artificial leather, also called synthetic leather, is a material intended to substitute for leather in upholstery, clothing, footwear, and other uses where a leather-like finish is desired but the actual material is cost prohibitive or unsuitable due to practical or ethical concerns. Artificial leather is known under many names, including ''leatherette'', ''imitation leather'', ''faux leather'', ''Veganism, vegan leather'', ''PU leather'' (polyurethane), and ''pleather''. Uses Artificial leathers are often used in clothing fabrics, furniture upholstery, water craft upholstery, and automotive interiors. One of its primary advantages, especially in cars, is that it requires little maintenance in comparison to leather, and does not crack or fade easily, though the surface of some artificial leathers may rub and wear off with time. Artificial leather made from polyurethane is washable, but varieties made from polyvinyl chloride (PVC) are not easily cleaned. Fashion Depending on ...

6L6GC
6L6 is the designator for a beam power tube introduced by Radio Corporation of America in April 1936 and marketed for application as a power amplifier for audio frequencies.J. F. Dreyer Jr."The Beam Power Output Tube" New York: McGraw-Hill, ''Electronics'', April 1936, pp. 18 - 21, 35 The 6L6 is a beam tetrode that utilizes formation of a low potential space charge region between the anode and screen grid to return anode secondary emission electrons to the anode and offers significant performance improvements over power pentodes. The 6L6 was the first successful beam power tube marketed. In the 21st century, variants of the 6L6 are manufactured and used in some high fidelity audio amplifiers and musical instrument amplifiers. History In the UK, three engineers at EMI (Isaac Shoenberg, Cabot Bull and Sidney Rodda) had developed and filed patents in 1933 and 1934 on an output tetrode that utilized novel electrode structures to form electron beams to create a dense space charge ...

12AU7
The 12AU7 and its variants are miniature nine-pin (B9A base) medium-gain dual-triode vacuum tubes. It belongs to a large family of dual-triode vacuum tubes which share the same pinout (RETMA tube designation, RETMA 9A). 12AU7 is also known in Europe under its Mullard–Philips tube designation ECC82. There are many equivalent tubes with different names, some identical, some designed for ruggedness, long life, or other characteristics; examples are the US military 5814A and the European special-quality ECC802 and E82CC. The tube is popular in hi-fi vacuum tube audio as a low-noise line amplifier, driver (especially for tone stacks), and phase-inverter in vacuum tube push–pull amplifier circuits. It was widely used, in special-quality versions such as 5814A, in pre-semiconductor digital computer circuitry. Use of special-quality versions outside of the purpose they were designed for may not be optimal; for example, a version for digital computers may be designed for long life wi ...

Vintage 30
In winemaking, vintage is the process of picking grapes to create wine. A vintage wine is one made from grapes that were all, or primarily, grown and harvested in a single specified year. In certain wines, it can denote quality, as in Port wine, where Port houses make and declare vintage Port in their best years. From this tradition, a common, though not strictly correct, usage applies the term to any wine that is perceived to be particularly old or of a particularly high quality. Most countries allow a vintage wine to include a portion of wine that is not from the year denoted on the label. In Chile and South Africa, the requirement is 75% same-year content for vintage-dated wine. In Australia, New Zealand, and the member states of the European Union, the requirement is 85%. In the United States, the requirement is 85%, unless the wine is designated with an AVA, (e.g., Napa Valley), in which case it is 95%. Technically, the 85% rule in the United States applies equally to impo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5881
Tung-Sol was an American manufacturer of electronics, mainly Lamp (electrical component), lamps and vacuum tubes. History In 1904, the company started as a small business in New York City, with Harvey Wilson Harper and two brothers, Herbert E. and Herbert C. Plass. The Plass brothers operated the Howard Electric Novelty Company at the time in New York City. Harper had received a patent in 1904 for a "Machine for Making Incandescent-Electric-Lamp Bulbs," for a machine improving the production of bulbs. The company invented electric lights for Christmas trees as well as production of 2-inch 2-rail toy train model equipment between 1904 and 1906. In 1911, the company stopped its production of the trains in order to concentrate on bulbs and radio tubes productions. Lamp experience and beginnings Harper had worked since 1897 with miniature lamps. By 1900 he worked at General Electric as head of the miniature lamp department. In 1907, the Howard Miniature Lamp Company moved to 327 Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tolex
Tolex is a trade name for a flexible, waterproof, vinyl material used as a cover material for books, upholstery, guitar amplifiers, cases, and other products. Tolex was filed as a trademark on August 30, 1945 by the General Tire, and was registered as "a plastic sheet and film material for book binding and case covering for speakers and amplifiers". General Tire was disconglomerated, and the trademark expired in 2005. TOLEX is a Canadian trademark and brand of OMNOVA Solutions, Fairlawn, Ohio, now part of Synthomer.

12AX7
12AX7 (also known as ECC83) is a miniature dual-triode vacuum tube with high voltage gain (electronics), gain. Developed around 1946 by RCA engineers in Camden, New Jersey, under developmental number A-4522, it was released for public sale under the 12AX7 identifier on September 15, 1947. The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications. As a popular choice for guitar tube amplifiers, its ongoing use in such equipment makes it one of the few small-signal vacuum tubes in continuous production since it was introduced. History The 12AX7 is a twin triode basically composed of two of the triodes from a 6AV6, a double diode triode. The 6AV6 is a miniature repackaging (with just a single cathode) of the triode and twin diodes from the octal 6SQ7 (a double-diode triode used in AM radios), which itself is very similar to the older type 75 triode-diode dating from 1930. Application The 12AX7 is a high-gain (typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EL84
The EL84 is a vacuum tube of the power pentode type. It is used in the power-output stages of audio amplifiers, most commonly now in guitar amplifiers, but originally in radios. The EL84 is smaller and more sensitive than the octal 6V6 that was widely used around the world until the 1960s. An interchangeable North American type is the ''6BQ5'' (the RETMA tube designation name for the EL84). The EL84 was developed to eliminate the need for a driver tube in radios, so it has rather more gain than is usual in a power pentode. Eliminating a preamplifier triode in radios made them cheaper. Manufacturers were quick to adopt it in general use, and they are found in many old European tube-radios and other audio equipment. A single EL84 was used in low-cost equipment, and a push–pull pair for lower distortion and higher power. In common with all 'E' prefix tubes, using the Mullard–Philips tube designation, it has a heater voltage of 6.3V. It can produce 17W output in Class AB1 i ...
