Miniature heptode primarily intended to perform the combined functions of mixer and oscillator in automobile radio receivers. Specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.

Miniature pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers. The tube is specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.

Miniature double didoe, high-mu triode intended for use as a second detector audio amplifier. It is designed for operation where the heater and plate voltages are supplied directly from a 12-volt automotive storage battery.

Telefunken Brand. Miniature medium-mu twin triode intended for service in radio and television receivers or in audio amplifiers.

Miniature remote-cutoff pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers.

Miniature power pentode primarily designed for use as the video output amplifier in television receivers. Features of the tube include high transconductance, low interelectrode capacitances, and high power sensitivity.

Miniature twin double-plate triode with each section having a grid and two plates brought out to separate base pins.

Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.

Variable-mu pentode amplifier in the octal glass construction. It is suitable for use with AVC in RF and IF amplifier and minimizes cross modulation.

Transmitting beam power amplifier.

Miniature type of medium-mu twin triode intended especially for coverter service in ac/dc FM and AM receivers. In such service, one triode unit may be used as a mixer, and the other as an oscillator.

New Old Stock (N.O.S.) tube. 25CD6GB is identical to the 6CD6GA except with different heater ratings. Beam power tube, octal base.

Power-amplifier tube of the all-metal type for use in the output stage of transformerless (ac/dc) radio receivers, especially those designed to have ample reserve of power-delivering bilities.

Glass octal type used as horizontal-deflection amplifier in color television receivers.

Duodecar type used as horizontal-deflection amplifier in television receivers.

Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. It has high power sensitivity and high efficiency at relatively low plate and screen voltages.

Half-wave rectifier in the 7 pin miniature construction. Features of the tube are a 100mA. heater with 20 second warm-up time.

General purpose triode designed for service as an oscillator, detector, or amplifier.

The 3A4 is designed for use in compact, lightweight, portable equipment. The relatively large filament employed in the 3A4 enables it to supply the high peak currents required in RF power applications.

9-pin miniature double triode with separate indirectly heated cathodes. It is designed for use in amplifier, mixer, oscillator, multivibrator and clamp circuits. The useful frequency range extends through the VHF range.
