A biasing arrangement comprising: a pair of gate biasing resistors for Field Effect Transistors forming a push-pull amplifier, and a constant-current supplying means having two output terminals for supplying stabilized gate bias voltages to the transistors. The constant-current supplying means can be adjusted manually or automatically for setting a suitable operation point of the transistors and for balancing their bias voltages. By this arrangement, amplifiers can have a simplified structure. This arrangement greatly simplifies biasing means which also can be easily regulated.
