Abstract (en)
[origin: CA1202059A] In addition to the correction magnets commonly used in the electron-gun system of a color-picture tube for color purity and dynamic convergence, one or more additional correction magnets are fixed in or on the electron-gun system. During final adjustment of the color-picture tube, the usual and additional correction magnets are adjusted in turn using the same magnetizer.
