e/Grid bias

Information
has gloss	eng: 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 the positively charged anode. Bias point in small-signal applications is set to minimize distortion and achieve sufficiently low power draw. In high-power applications, biasing is typically set for maximum available output power or voltage, with a secondary target of either low distortion or high efficiency.
lexicalization	eng: Grid bias
instance of	(noun) electronic device consisting of a system of electrodes arranged in an evacuated glass or metal envelope electron tube, tube, thermionic tube, vacuum tube, thermionic vacuum tube, thermionic valve
