Abstract :
A description is given of the main electron-optical, electrical, and mechanical features of the deflection yoke that provides automatic convergence in the 20AX system. Sectionally wound saddle coils are used, and the shells in which they are mounted incorporate reference pieces to minimize assembly tolerances. An easy to operate assembly of multi-pole magnet rings provides for static convergence, color purity, and raster symmetry adjustment.
