| 摘要 |
The present invention provides a color picture tube apparatus in which YV and top and bottom trapezoidal distortions can be adjusted optimally even in a toroidal coil. A deflection yoke includes a horizontal deflection coil, a vertical deflection coil, and a ferrite core. The ferrite core is divided into an upper core 6 and a lower core 7. The vertical deflection coil is toroidally wound around each of the upper core 6 and the lower core 7. An upper core left coil 32 and an upper core right coil 34 are separated via a first intermediate tap 15, and a lower core left coil 34 and a lower core right coil 35 are separated via a second intermediate tap 26. A variable resistor that is connected to each of the coils in parallel and that is connected to at least either of the first or second intermediate tap 15 or 26 is provided.
