<p>Cathode ray tube comprising a deflection unit having a field deflection winding with two diametrically opposite field deflection coils and a line deflection winding with two diametrically opposite line deflection coils. Each coil has a front end segment (15, 18) , a rear end segment and conductors extending between the front and the rear end segments. In order to correct a rotation of the horizontal lines of the raster with respect to the horizontal axis, which rotation is produced by tolerance errors two plate-shaped parts 21, 21' of a soft magnetic material are arranged near the front end segments (15) of the two line deflection coils (11, 11') in positions which coincide with two oppositely located vertices of a rectangle whose diagonals intersect each other on the longitudinal axis of the deflection unit and in which positions parts of the line deflection coil front end segments (11, 11') are located opposite parts of the field deflection coil front end segments (12, 12').</p> |
