John Linsley Hood
John Laurence Linsley-Hood (9 February 1925 in Wandsworth, London – 11 March 2004 in Taunton, Somerset) was an English electronics engineer and designer of audio components. He was educated at Reading School, Acton Polytechnic, the Royal Technical College (Glasgow) and after World War Two, at Reading University. In 1942 Linsley-Hood joined the G.E.C. Research Laboratories at Wembley, working on magnetron development as junior member of a team. Joining the RAF aircrew in 1943, he was transferred to work on radar, then subsequently worked with T.R.E. (Malvern) overseas. After returning to university, Linsley-Hood joined the Windscale Research Laboratories of the Atomic Energy Authority. He was in charge of the electronics team in the Research Laboratories of British Cellophane Ltd. from 1954. John Linsley-Hood is best remembered by hi-fi enthusiasts for his "Simple Class A Amplifier", [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wandsworth
Wandsworth Town () is a district of south London, within the London Borough of Wandsworth southwest of Charing Cross. The area is identified in the London Plan The London Plan is the statutory spatial development strategy for the Greater London area in the United Kingdom that is written by the Mayor of London and published by the Greater London Authority. The regional planning document was first pu ... as one of 35 major centres in Greater London. Toponymy Wandsworth takes its name from the River Wandle, which enters the River Thames, Thames at Wandsworth. Wandsworth appears in Domesday Book of 1086 as ''Wandesorde'' and ''Wendelesorde''. This means 'enclosure of (a man named) Waendel', whose name is also lent to the River Wandle. To distinguish it from the London Borough of Wandsworth, and historically from the Wandsworth District (Metropolis), Wandsworth District of the Metropolis and the Metropolitan Borough of Wandsworth, which all covered larger areas, it is al ...

Telecommunications Research Establishment
The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man." The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE. History TRE is best known for work on defensive and offensive radar. TRE also made substantial contributions to radio-navigation and to jamming enemy radio-navigation. Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Williamson Amplifier
The Williamson amplifier is a four-stage, push-pull, Class A triode-output valve audio power amplifier designed by D. T. N. Williamson during World War II. The original circuit, published in 1947 and addressed to the worldwide do it yourself community, set the standard of high fidelity sound reproduction and served as a benchmark or reference amplifier design throughout the 1950s. The original circuit was copied by hundreds of thousands amateurs worldwide. It was an absolute favourite on the DIY scene of the 1950s, and in the beginning of the decade also dominated British and North American markets for factory-assembled amplifiers. The Williamson circuit was based on the 1934 '' Wireless World Quality Amplifier'' by Walter Cocking, with an additional error amplifier stage and a global negative feedback loop. Deep feedback, triode-connected KT66 power tetrodes, conservative choice of standing currents, and the use of wide-bandwidth output transformer all contributed to the ...

Electronic Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a Signal (information theory), signal (a time-varying voltage or Electric current, current). It may increase the power (physics), power significantly, or its main effect may be to boost the voltage or current (power amplifier, power, voltage or current amplifier). It is a two-port network, two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (electronics), gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator (electronics), attenuator). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Cellophane
British Cellophane Ltd (BCL) was a joint venture company formed in 1935 between La Cellophane SA and Courtaulds, when they began building a major factory for producing Cellophane in Bridgwater, Somerset, England. History 19th century The process for manufacturing cellulose film from viscose was discovered by three English chemists, Charles Frederick Cross, Edward John Bevan and Clayton Beadle in 1898. 20th century There followed a series of joint ventures and technology transfers among a number of companies predominantly in the UK and France. However, it was not until 1913 that Jacques Brandenberger, Dr Jacques Brandenberger brought thin transparent cellulose film into true commercial production at the La Cellophane SA'' factory in Bezons, France. In 1937 British Cellophane set up production on a site in Bridgwater, when unemployment levels in the town were high. The new buildings covered of the former Manor of Sydenham, Sydenham Manor fields, and had direct railway access. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
