How do vacuum tubes work in amplifiers
WebApr 19, 2024 · Vacuum tubes are (by their nature) high voltage, low current devices; semiconductors are by contrast lower voltage, higher current devices. The failure mode for vacuum tubes in case of over-voltage is mostly arcing. This does damage the tube, but if it's caught in time it need not be catastrophic. WebFeb 1, 2024 · Vacuum tubes used in amplifiers are also called “thermionic valves” referring to the way that temperature causes the release and flow of electrons. The basic type we …
