Part of the output of a push pull Clapp oscillator is rectified and smoothed to provide a voltage for stabilizing the oscillation amplitude, the control voltage being fed to the base of a transistor that acts as a variable resistance in a voltage divider connected to the bases of the push pull oscillator transistors, the controlled conduction of the voltage divider transistor acting to control the working points of the oscillator transistors so as to maintain a substantially constant oscillation amplitude. |
