In a deflection apparatus which corrects for inside pincushion distortion, a deflection winding (L H ) and a retrace capacitance (C RD ) form a retrace resonance circuit (27) during a retrace interval. A trace capacitance (C s ) forms a trace resonant circuit with the deflection winding (L H ) during the trace interval. A circuit branch (60), that includes a second capacitance (C₄) and an inductance (L₂), is coupled to the trace capacitance (C s ) during the trace interval to form a second resonant circuit with the trace capacitance (C s ) having a resonance frequency that is substantially higher during the trace interval than that of the trace resonant circuit. A current in the circuit branch (60), that is modulated in accordance with the modulated voltage, modulates the trace parabolic voltage across the trace capacitance (C s ) in a manner to reduce inside pincushion distortion. The trace capacitance (C s ) acts as a bypass capacitor around the inductance (L₂) during retrace to prevent the inductance (L₂) from affecting the retrace voltage.
