ABSTRACT:
A deflection yoke includes a coil frame having guide members provided at the front and rear ends of a flared core or coil bobbin. Each guide member has a plurality of circumferentially arrayed finger members spaced so as to define slots having a predetermined width. Each finger member is provided with a pair of projections extending outwardly in the radial direction of the coil frame such that the projections define an annular channel. A troidal-type winding is wound on the coil frame between corresponding ones of the slots, and a saddle-type winding is wound on the coil frame through the annular channel so as to extend along the inside surface of the coil frame.
