Grid-leak detector — A grid leak detector is a combination diode rectifier and audio amplifier used as a detector in vacuum tube A.M. radio receivers. In the circuit, the grid of the detector usually a low mu or medium mu triode is connected to the secondary of the… … Wikipedia
grid leak — noun : a resistor used in parallel with a capacitor in the grid circuit of a vacuum tube to limit grid bias by drawing off excess electrons that accumulate on the tube grid * * * Electronics. a high resistance device that permits excessive… … Useful english dictionary
Grid bias — is a DC voltage applied to electron tubes (or valves in British English) with three electrodes or more, such as triodes. The control grid (usually the first grid) of these devices is used to control the electron flow from the heated cathode to… … Wikipedia
Plate detector (radio) — A plate detector is a vacuum tube detector circuit used in A.M. radios. This circuit employs a tube with an indirectly heated cathode, typically a medium mu triode, or a tetrode or pentode with a sharp cut off control grid. Rectification of R.F.… … Wikipedia
Valve audio amplifier - technical — Circuitry and performance Characteristics of valves Valves are very high input impedance (near infinite in most circuits) and high output impedance devices. They are also high voltage / low current devices.While valves themselves are described… … Wikipedia
Battery (vacuum tube) — In electronics, vacuum tubes were traditionally powered by batteries. Each battery had a different designation depending on which vacuum tube element it was associated with.Initially, the only such device was a diode with only a filament… … 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
Space charge — is a concept in which excess electric charge is treated as a continuum of charge distributed over a region of space (either a volume or an area) rather than distinct point like charges. This model typically applies when charge carriers have been… … Wikipedia
Wunderlich (vacuum tube) — Wunderlich refers to a series of vacuum tubes introduced in the early 1930s. Wunderichs were designed to be used as full wave detectors in AM radio receivers. However, because of their unusual design, they were rarely used in commercially… … Wikipedia
Vacuum tube — This article is about the electronic device. For experiments in an evacuated pipe, see free fall. For the transport system, see pneumatic tube. Modern vacuum tubes, mostly miniature style In electronics, a vacuum tube, electron tube (in North… … Wikipedia
Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… … Wikipedia
