Transistor: Transistors are among the basic electronic components in the world HiFi- or audio technology. Basically, you can think of a transistor quite simply as an electrically controllable switch. However, the operating principle of a transistor is not based on a mechanical switching function, as known from a light switch or relay, but on semiconductor technology. In addition - and this is a particularly important point - transistors are not only suitable for switching currents, but also for amplification.
