Abstract
From the standpoint of improved TV receiver performance, the RCA nuvistor 1 electron tube represents a major breakthrough, particularly with respect to features of small size, low noise, low power drain, and greater reliability. In the design assembly and processing of the nuvistor, most of the known causes of tube failure on life have been minimized or eliminated. Figure 1 is a cutaway view which shows the strong ceramic basewafer that supports the small light cylindrical electrodes. The cylindrical electrode structure permits the critical tube elements to be assembled in a simple fixture, thus making possible close-spaced electrode assembly with accuracy and uniformity. The type 6CW4 is a nuvistor tube designed for use in VHF television tuner RF amplifiers.
