ABSTRACT:
A distribution type delay line particularly adapted for use in a color television receiver and for mass production is disclosed. A bobbin with several axially spaced flanges defining several winding or coil slots therebetween is combined with a circuit of series-connected grounding electrode windings or coils each wound in each slot and each consisting of a predetermined number of turns of insulated wire and/or a circuit of series-connected shield windings each wound in each slot and each consisting of a predetermined number of turns of insulated wire, and a circuit of series-connected signal windings each wound in each slot outwardly and/or inwardly of the grounding electrode and/or shield windings and each consisting of a predetermined number of turns of insulated wire, the grounding electrode and shield windings being wound in the opposite directions so that the magnetic fluxes induced thereacross may be cancelled by each other.
