TL;DR: The 6CW4 is a nuvistor tube designed for use in VHF television tuner RF amplifiers as mentioned in this paper, which has a cylindrical electrode structure that allows the critical tube elements to be assembled in a simple fixture.
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.

TL;DR: The Nuvistor small-signal tetrode as mentioned in this paper has great potential for use in the intermediate-frequency stages of new television receivers, and provides the circuit designer with a new tube capable of superior performance in this wideband amplifier application.
Abstract: The Nuvistor small-signal tetrode, a modern and unique development in the design and manufacture of electron tubes, has great potential for use in the intermediate-frequency stages of new television receivers. The Nuvistor provides the circuit designer with a new tube capable of superior performance in this wideband amplifier application. In addition to its high figure of merit, the Nuvistor tetrode has many other advantages pertinent to its use in television receiver circuits. This paper briefly describes the constructional features of the Nuvistor which contribute to its high performance, and gives detailed comparison of laboratory models of two- and three-stage stagger-tuned if amplifiers.
