Headphone Audio Amplifier with Balance Control

This is a relatively simple headphone audio amplifier circuit that features a single amplification stage plus emitter-follower for both Left and Right audio channels, with balance control.

The circuit uses a total of 24 simple electronic components (not including the power supply). 4 of these components are transistors (BC549C), where 2 are used for each channel (left/right), one amplifier and one emitter follower.

The gain of this amplifier is less than 10 - but that's still a lot if you think about it ;)

The amplifier's output is designed to drive low-medium impedance headphones.
