A low cost approach to the 94° deflection system

The advent of the 1–1/8 inch diameter 94° Cathode Ray Tubes (23DAPU type) allows a new and different approach to sweep system design. With horizontal and vertical sweep components previously optimized as to cost and performance, the increase in sensitivity derived from the smaller neck 94° CRT does noi offer any appreciable system saving. However the increase in sensitivity now permits the design of a shorter, more economical yoke that provides circuit performance equivalent to previous 90° systems. The shorter yoke also allows a new gun arrangement that can shorten the overall CRT length by approximately 2 inches.
