Transistor oscillator circuit having a resonant-circuit or crystal-controlled oscillator realized by a feedback differential amplifier and provided for driving a mixture stage including a pair of transistors forming the oscillator and having a current-carrying output connected to a respective input of the mixture stage, the latter being of symmetrical construction, a low pass filter also connected to the current carrying output of the oscillator, a common control amplifier having an output, and respective inputs connected to the oscillator via the low pass filter, and means for feeding back the output of the control amplifier to the oscillator in the sense of negative feedback.
