ABSTRACT:
A self-converging color television display system utilizes a saddle-toroid deflection yoke. The length of the horizontal coil conductors adjacent the flared picture tube portion is limited to reduce stored energy. The length of the core also is limited and disposed longitudinally between the end turns of the horizontal saddle coils at a position to mitigate convergence trilemma as well as North-South pincushion distortion.
