WebSep 1, 2024 · Tube amplifiers use vacuum tubes to amplify sound. The first step is to generate an alternating current (AC) signal. This is done by passing a current through a coil of wire, which produces a magnetic field. The magnetic field then interacts with the electrons in the tube, which causes them to flow in an alternating current. WebMay 13, 2024 · The vacuum tube works on the basis of a few basic principles.
