The control grid is an electrode used in amplifying thermionic valves such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode electrode. The contro

A single-ended triode is a vacuum tube electronic amplifier that uses a single triode to produce an output, in contrast to a push–pull amplifier which uses a pair of devices with antiphase inputs to g
