WebWhat Class A really means is that “Grid bias and alternating grid voltages are such that plate current in a. tube flows at all times”. That’s the entire definition from the RCA Tube Manual: the Ultimate Authority itself. To make it simpler, think of a tube in the British sense: It’s a “valve". All Class A means is that the valve would ... WebThe advantages of a class ab amplifier include the following. The main advantage of the class AB amplifier is the elimination of cross-over distortion. It is a linear amplifier because the amplitude and the phase of the output signal are the same as the input. Preferred for radios, audio systems, and TV receivers.
