Abstract
In a deflecting yoke of an in-line type color picture tube, a pair of saturable reactors responsive to vertical deflection is connected to the horizontal deflecting coils so that horizontal deflection currents respectively flowing in two horizontal deflecting coils are controlled differentially in accordance with the degree of the vertical deflection, thereby minimizing raster distortion. Each of the saturable reactors may comprise a series connection of two coils connected to the vertical deflecting coils, and another series connection of two coils connected to the horizontal deflecting coils. The first-mentioned series connection may be omitted by positioning the second-mentioned series connection so that leakage flux from the vertical deflecting coils can be picked up. The core or cores of each of the saturable reactors are magnetically biased by a permanent magnet. A single disk-like magnet may be rotatably held to be in contact with two parallel cores so that rotation of the magnet results in change in impedance of the reactor.
