A horizontal deflection circuit output stage includes a trace capacitor for developing a trace voltage. A retrace capacitance is coupled to a deflection winding to form a retrace resonant circuit with the deflection winding, during a retrace interval of a deflection cycle. A rectifier for rectifying a retrace pulse voltage developed in the retrace capacitance. A switching transistor is coupled to the inductance and to the trace capacitor for applying the rectified retrace pulse voltage to the inductance to generate a current in the inductance. The inductance current is coupled to the trace capacitor, during the trace interval, to provide for linearity correction. The rectifier is coupled to the switching transistor for producing a rectified control signal at a control terminal of the switching transistor to cause a change of state in the switching transistor, during the retrace interval.
