Valve RF amplifier — A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical , typically (but not exclusively) radio frequency signals.Low to medium power valve amplifiers for frequencies below… … Wikipedia
Valve amplifier — A valve amplifier or tube amplifier is a type of electronic amplifier that make use of vacuum tubes instead of solid state semiconductor devices (such as transistors). As any other electronic amplifier they serve to increase the power and/or… … Wikipedia
Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… … Wikipedia
Pentagrid converter — For other types of frequency converters please, see Frequency converter. The pentagrid converter is a radio receiving valve (vacuum tube) with five grids used as the frequency mixer stage of a superheterodyne radio receiver. Grids of a 12SA7GT… … Wikipedia
Control grid — The control grid is an electrode used in thermionic valves (vacuum tubes) used to modulate the flow of electrons in the cathode to anode or plate circuit. Contents 1 Operation 2 Construction 3 Effects of grid position … Wikipedia
List of vacuum tubes — This is a list of vacuum tubes or thermionic valves. Before the advent of semiconductor devices, hundreds of tube types were used in consumer and industrial electronics; today only a few types are still used in specialized applications. Contents… … Wikipedia
Tube sound — (or valve sound) is the characteristic sound associated with a vacuum tube based audio amplifiers. Some audiophiles prefer the sound that is produced by the distortion characteristics of tube based amplifiers. The audible significance of tube… … Wikipedia
Electrometer — An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. There are many different types, ranging from historical hand made mechanical instruments to high precision electronic devices. Modern… … Wikipedia
Mullard-Philips tube designation — In Europe, the principal method of numbering vacuum tubes (or thermionic valves , as they are referred to in Europe and Australia, etc.) was the nomenclature developed and used by Mullard in the UK and applied Europe wide thanks to their… … Wikipedia
12AX7 — is a miniature dual triode vacuum tube with high voltage gain. It is believed to have been originally developed in 1946 by RCA engineers in Harrison, New Jersey under developmental number A 4522. It was released for public sale under the 12AX7… … Wikipedia
Distributed amplifier — Distributed amplifiers are circuit designs that incorporate transmission line theory into traditional amplifier design to obtain a larger gain bandwidth product than is realizable by conventional circuits. N stage traveling wave amplifier … Wikipedia
