In audio transformer applications, magnetic saturation causes low-frequency harmonic distortion to increase steadily for low-frequency signals as they increase in level beyond a threshold. In general, materials with a higher permeability tend to saturate at a lower flux density. In general, permeability also varies inversely with frequency.

day audio- frequency amplifiers is the transformer used to couple the plate circuit of one tube to the grid circuit of the next. It is the transformer which determines to a large degree the quality of the sound output and hence the use- fulness of the amplifier. While the aver- age transformer coupled amplifier does
