Biasing amplifier transistors

Описание к видео Biasing amplifier transistors

Biasing the pair of power transistors (NPN + PNP) in the output amplifier of my function generator (TR-0458/B). The previous owner probably changed the transistors, but they also needed to be re-biased, as their base to emitter voltage drop was higher. They were under-biased, causing signal distortion. The same can apply to bipolar discrete transistor audio amplifiers.
