"Basically the audio MagAmp works similarly to an audio tube amplifier what material is not of a vacuum tube but of a amorphous core. One core typically has two copper windings: a control winding for the input signal and a working winding for the amplified input signal. Similar to the tube amplifier, there is an operating point on the characteristic curve in the idle state (@ no input signal). However, the characteristic curve for the MagAmp is made up of B (magnetic flux: output voltage) and H (magnetizing force: DC current). Depending on the pre-magnetization of the core (DC bias), a idle current occurs, typically in the middle of the characteristic curve, so that Class A operation is possible. From this point, the magnetic flux changes up or down along the steep characteristic curve depending on the applied input signal. This is basically where the actual magnetic amplification happens. While the tube is operated with a continuous direct current, the MagAmp requires a pulsed direct current (high frequency) due to the magnetic hysteresis, characterized by a coil (working winding) in series with a diode. By connecting several magnetic cores, various basic circuits can be implemented, such as push-pull"
