Abstract
A single degaussing coil (20) for a kinescope (10) has a first portion (20a) located along a first side of the base of a generally pyrimidal kinescope envelope or bulb. Second and third portions of the coil extend along portions of second and third sides of the base and are joined by a fourth portion of the coil lying between the juncture of the neck and the bulb. The first portion 20a tends to degauss the shadow-mask (332) while the diametrically opposite portion, due to a tilt in the axis of the single coil in relation to the tube axis, lie adjacent the small end of an internal magnetic shield of frusto-conical shape and hence more efficiently magnetically interact therewith. The single tilted coil requires lower degaussing energies in operation and a simpler wiring in manufacture.
