。(b) Prior Art Conventionally, a ferrite sheet has been attached to the inner surface of the deflection yoke in order to correct the convergence of the color cathode ray tube. To install this ferrite sheet, check the test pattern projected on the cathode ray tube with the deflection yoke attached to the tube, and if the ferrite sheet is not installed in the optimal position, remove the deflection yoke from the tube and try again. It is necessary to attach the ferrite sheet to the optimal position predicted by the quantity, reinstall it to the cathode ray tube, check the test pattern, and repeat the above operations over and over again until the ferrite sheet is in the optimal position, which is cumbersome. It was a task that required skill.
