Abstract
Auxiliary deflection coils are connected to horizontal deflection coils. Each auxiliary deflection coil is disposed in the intermediate region between the inner peripheral end adjacent to a window and the outer peripheral end. Each horizontal deflection coil is dividable into three regions extending from its winding introductory part to its winding terminal part. A variable inductance coil is connected in parallel with the intermediate region to control the horizontal deflection current flowing across the horizontal deflection coil. The variable inductance coil has a cylindrical core installed in a hollow space of a bobbin and a coil connected in parallel with the auxiliary coil. A disc core is provided adjacent to the coil. The disc core has an end face larger in area than an end face of the cylindrical core.
