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.

This paper describes the circuits which process the detected video signal and extract from it the various sub-signals required by the receiver. The transistor requirements for these circuits are discussed and recommended transistors and circuits are shown. Performance data and design considerations are included to enable the circuit designer to choose the particular features which are applicable for his requirements.

A transistorized vertical deflection system has been developed to scan a 90-degree, 14-inch picture tube at 14 KV accelerating voltage. This system consists of two transistors in a common-emitter multivibrator to form a vertical oscillator, one transistor as a driver and one output transistor, and the system is supplied power from a 12-volt d-c source. To prevent decentering of the raster, due to the d-c component of current in the deflection-coils, the output stage is coupled to these coils by means of an isolation transformer. Feedback networks are introduced to correct for the non-linear characteristics of the transistors, and to predistort the input waveform to the output transistor in order to compensate for the non-linearity of the transformer.

With the advent of a battery operated TV receiver, the need arises to develop circuits, especially sweep circuits, which will produce full scan with very little component weight and power consumption. These requirements are considered of paramount importance in the design of the vertical deflection system presented in this paper.

A unique drift-free direct-coupled amplifier has been developed employing a clipper and an RC integrating circuit in a feedback loop for stability. Equations are developed and computed and experimental curves are given for amplitude and phase-shift response as a function of frequency showing an extremely sharp power drop-off at the low end.

Recent developments in the art have dictated the division of this paper into two component parts. The first deals with a quadrapolar, magnetic lens of rotational non-symmetry used to achieve scan magnification with a television cathode ray tube. The second concerns the development of a negative, electrostatic, gauze lens exhibiting full rotational symmetry which is also used to provide scan magnification.

This paper describes a five-transistor automobile receiver designed to use newly developed RCA drift transistors. These drift transistors, which inherently have a high maximum available gain and low feedback capacitance, provide good performance with a minimum number of stages, thus contributing to low over-all circuit cost.
