PURPOSE:To correct the right and left pin distortion without remaining an intermediate pin distortion with simple circuit configuration. CONSTITUTION:To a transistor 1, the serial circuit of a variable direct current voltage source 2 and a choke coil 3 is connected in parallel, and from the variable direct current voltage source 2, the parabolic wave-shaped voltage of the vertical cycle is supplied through the choke coil 3 to the transistor 1, the right and left pin distortion is corrected, and to the transistor 1, the serial circuit of a primary side winding 9a of a horizontal deflection coil 6, an S-character correction capacitor 7, a correction coil 8 and a transformer 9 for modulation is connected in parallel, and the parabolic wave-shaped current of the vertical cycle is supplied to a secondary side winding 9b of the transformer 9 for modulation and the intermediate pin distortion is canceled. |
