(under the class definition) Subject matter wherein the oscillator includes a source of electrical energy for supplying power to the oscillator or for supplying biasing potential to the electrodes of the active element of the oscillator.

71, for oscillators wherein the source of power is raw (unrectified) alternating current.
175, for oscillators having means to compensate for drift of electrode potential of the active element of the oscillator, where such potential drift would cause an undesired change in oscillator frequency.
183, for oscillators wherein the amplitude of the generated oscillations is controlled by adjusting or varying the biasing potential of a electrode, or electrodes, of the active element of the oscillator.
