The vertical deflection coils are wound around the ferrite core of the deflection yoke with pyramidal configuration. The method has the steps of forming the first layer by winding coil with gaps, forming the second layer by winding coil above the gap of the first layer, and forming the layers above them in the same way. The yoke prevents scattering of convergence and inductance values of the coil.
