From an audio signal, this circuit gets two signals of the same amplitude and opposite phases. This setting is widely used in bridge amplifiers (BTL). Transistors may be commonly used as BC series.
This circuit is as shown in a 1976 technical documentation. It can currently be assembled with any...
Equivalent transistors, like the BC548 and BC558 pair can be used in this circuit that we find in an...
