Vox AC30
The Vox AC30 is a guitar amplifier manufactured by Vox. It was introduced in 1958 to meet the growing demand for louder amplifiers. Characterised by its "jangly" high-end sound it has become widely recognized by British musicians and others, such as George Harrison and John Lennon of the Beatles, Bill Wyman of the Rolling Stones, Brian May of Queen, Dave Davies of the Kinks and Hank Marvin. History The Vox AC30 was originally introduced in 1959 at Hank Marvin's request as the "big brother" of the fifteen watt (15 W) AC15 model, Vox's original flagship amplifier, because the AC15 was not loud enough with the screaming fans at Cliff Richard's concerts. The AC15 was powered by a pair of EL84 tubes, an EF86-driven "Normal" channel, an ECC83-driven "Vib-Trem" channel, and rectified by an EZ81. The original first-generation AC30 used a GZ34 tube rectifier, three ECC83s (12AX7) for the Normal channel and the tremolo/vibrato oscillator/modulator circuits, one ECC81 (12AT7) phase inver ...

EF86
The EF86 is a high transconductance sharp cutoff pentode vacuum tube with Noval (B9A) base for audio-frequency applications. It was introduced by the Mullard company in 1953 and was produced by Philips, Mullard, Telefunken, Valvo, and GEC among others. It is very similar electrically to the octal base EF37A and the Rimlock base EF40. Unlike many pentodes it was designed specifically for audio applications, low noise and low microphony being claimed advantages, although a rubber-mounted vibration-resistant base was still recommended. It has much higher stage gain than any triode, which makes it susceptible to microphony. The EF86 was used in many preamplifier designs during the last decades of vacuum tube hi-fi development. An industrial variant of the tube is known as 6267. In the former Soviet Union a variant was also produced as type 6Zh32P (Russian: 6Ж32П.) EF86s were being produced in Russia in two versions under the Electro-Harmonix brand and in the Slovak Republic a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Korg
, founded as Keio Electronic Laboratories, is a Japanese multinational corporation that manufactures electronic musical instruments, audio processors and guitar pedals, recording equipment, and electronic tuners. Under the Vox brand name, they also manufacture guitar amplifiers and electric guitars. History Korg was founded in 1962 in Tokyo by Tsutomu Kato and Tadashi Osanai as ''Keio Gijutsu Kenkyujo Ltd.''. It later became because its offices were located near the Keio train line in Tokyo and Keio can be formed by combining the first letters of Kato and Osanai. Before founding the company, Kato ran a nightclub. Osanai, a Tokyo University graduate and noted accordionist, regularly performed at Kato's club accompanied by a Wurlitzer Sideman rhythm machine. Dissatisfied with the rhythm machine, Osanai convinced Kato to finance his efforts to build a better one.Julian Colbeck, Keyfax Omnibus Edition, MixBooks, 1996, p. 52.

Status Quo (band)
Status Quo are a British rock band that formed in 1962. The group originated in London as The Scorpions and was founded by Francis Rossi and Alan Lancaster while they were still schoolboys. After a number of lineup changes, which included the introduction of Rick Parfitt in 1967, the band became The Status Quo in 1967 and Status Quo in 1969. As of 2022, the group have been active for 60 consecutive years (despite announcing a breakup in 1984, they would play Live Aid the following year and resume normal activities in 1986). They have had over 60 chart hits in the UK - more than any other rock band - including "Pictures of Matchstick Men", "Down Down", "Rockin' All Over the World", " Whatever You Want", " In the Army Now", and "What You're Proposing". Twenty-two of these reached the Top 10 in the UK Singles Chart, and fifty-seven reached the Top 40. They have released over 100 singles and 33 albums, most of which were bestsellers. Since reaching number 5 on the UK albums chart i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solid State (electronics)
Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term "solid-state" became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. A semiconductor device works by controlling an electric current c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silicon
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to prepare it and characterize it in pure form. Its oxides form a family of anions known as silicates. Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust. It is widely distributed in space in cosmic dusts, planetoids, and planets as various forms of silicon dioxide ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dallas Arbiter
The Fuzz Face is an effects pedal for electric guitar, used also by some electric bass players. It is designed to produce a distorted sound referred to as "fuzz", originally achieved through accident such as broken electrical components or damaged speakers. History Arbiter Electronics Ltd. first issued the Fuzz Face in 1966. Later units bear the "Dallas Arbiter", "Dallas Music Industries Ltd.", "CBS/Arbiter Ltd." or "Dunlop Manufacturing Inc." name. The earliest units used germanium transistors. Silicon transistors were used in later editions of the pedal. Silicon transistors provided for a more stable operation, but have a different, harsher sound. The electronics are contained in a circular-shaped metal housing. Ivor Arbiter "got the idea for the round shape when he one day saw a microphone stand with a cast iron base".http://www.custom-sounds.com/epages/Gagar.sf/en_US/?ObjectPath=/Shops/CustomSounds/Categories/articles/fuzz "Fuzz Face" by David Morin The design was original ...

Vox AC50
The Vox AC50 is a guitar amplifier head and accompanying speaker cabinet manufactured by Vox. It was introduced in 1964 to meet the growing demand for louder amplifiers during the British Invasion era of rock and roll live performances. Most notable performers that used the AC50 was The Beatles as well as several other British pop rock bands during the mid to late 60's. Amp Head The head of the first AC50 MKI model originally had 2 inputs. 1 for a warmer "Normal" channel and another for a brighter "Brilliant" channel that sounds more comparable to a Vox AC30. The later MKII and MKIII models have 4 channels to meet the varied input needs of musicians. While the amp's output provided larger sound than the Vox AC30, the tube design called for two EL34 output tubes to achieve the power needed for tonal clarity. The preamp tubes were consistently one ECC82 (12AU7) tube and three ECC83 (12AX7) tubes. Early designs came outfitted with a GZ34 rectifier tube, while latter MKIII models hou ...

Electronic Circuit
An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. It is a type of electrical circuit and to be referred to as ''electronic'', rather than ''electrical'', generally at least one active component must be present. The combination of components and wires allows various simple and complex operations to be performed: signals can be amplified, computations can be performed, and data can be moved from one place to another. Circuits can be constructed of discrete components connected by individual pieces of wire, but today it is much more common to create interconnections by photolithographic techniques on a laminated substrate (a printed circuit board or PCB) and solder the components to these interconnections to create a finished circuit. In an integrated circuit or IC, the components and interconnections are formed on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alnico
Alnico is a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni), and cobalt (Co), hence the acronym ''al-ni-co''. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, and are used to make permanent magnets. Before the development of rare-earth magnets in the 1970s, they were the strongest type of permanent magnet. Other trade names for alloys in this family are: ''Alni, Alcomax, Hycomax, Columax'', and ''Ticonal''. The composition of alnico alloys is typically 8–12% Al, 15–26% Ni, 5–24% Co, up to 6% Cu, up to 1% Ti, and the rest is Fe. The development of alnico began in 1931, when T. Mishima in Japan discovered that an alloy of iron, nickel, and aluminium had a coercivity of , double that of the best magnet steels of the time. Properties Alnico alloys can be magnetised to produce strong magnetic fields and have a high coercivity (resistance to demagnetization), thus making strong permanent magn ...
