The leftmost side of the circuit is a current mirror circuit.

See attached

This circuit sets the value of the constant current source to the amplifier circuits on the right side. The value of the constant current is set by the emitter resistor connected at T17. It is called a current mirror circuit because the set current at this side is being mirrored or copied by ...
