3 Transistor Audio Amp (50 milliwatt) Here is a little audio amplifier similar to what you might find in a small transistor radio. The input stage is biased so that the supply voltage is divided equally across the two complimentary output transistors which are slightly biased in conduction by the diodes between the bases.

Headphone Amplifier Circuit using 3 Transistors – DIY. A headphone amplifier is a relatively low-power amplifier that boosts the low-voltage audio signal from a source device (be it a turntable, laptop, or a smartphone) to a sufficient level, such that it converts (or transduces) into sound waves by the speakers inside your headphones.

3-Transistor Headphone Amplifier. So, I was playing around trying to make the simplest amplifier I could. I ended up aiming for a low-power headphone amplifier, just to keep it simple, designed to drive ordinary cheap low-impedance headphones (iPod ear buds and the like, 20-30 ohm load at DC). The design works far better than it has any right ...

4 Transistor Class AB amplifier. Description. A very simple and easy to build class AB audio amplifier using four transistors is shown here. In class AB operation each output device conducts more than half of the input signal cycle. Up to 78% efficiency is possible with class AB designs and cross over distortion is reduced.
