In this particular design, Q1 and Q2 are wired in the common-emitter mode and drive the loudspeaker via push-pull transformer T2, and the anti-phase input drive is obtained via phase-splitting transformer T1. You have discrete class-a circuits that overdrive well like the infamous Neve console mic pre. The magnetic amplifier is only different from a transistor amplifier in that a small amount of DC current controls a large amount of AC current in the output instead of controlling a large amount of DC current in the output. For example, when you compare an amp with 4 output transistors (2 for positive waveform and 2 for negative waveform) with an amplifier that has 12 output transistors, the transistors on the 12 amp will work 1/3 as hard for the amp to push the same amount of. Depending on the type of transistor, the amount of gain available can vary substantially. it's an npn transistor. The Single NPN Transistor Audio Preamp.
