摘要： A color picture tube has the following dimensions. The outside diameter of the neck (2) is 22 - 23 mm. The nominal diameter of the circle of stem pins (11) outside the flared part (10) of the stem (9) welded at an edge of the neck is 15.24 mm. The maximum diameter of the base (15) bonded fixedly to the outside of the stem (9) is equal to or smaller than 23 mm. This color picture tube can achieve high resolution even if the outside diameter of the neck is reduced to power saving.
