Deflection unit for colour TV receiver - has inline colour tube with saddle deflection coils

摘要

Each deflection coil consists of two longitudinal wire bunches as well as front and back end windings. In order to reduce residual error of dynamic convergence, the cross-section of the wire bunch (9) consists at the junction with the front end winding of three different sections (13-15), of which the first (13) beginning at the coil's outer end is rectangular with a thickness (a). The second ends at the coil window is rectangular and its thickness (b) is smaller than (a). The third section n15) between the first two is trapezoidal, with thickness continuously changing from (a) to (b) thus forming a bridging section.
