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.

Triode, Double, Western Electric brand

Miniature type triode-pentode designed for use as an AF amplifier by triode section and AF power amplifier by pentode section in radio receivers.

Subminiature pentode for use as an A.F. power amplifier in portable equipment.

Heater-cathode type transmitting beam power amplifier in the 9 pin miniature construction. It is intended for use in compact, low-power mobile transmitters and in the low-power stages of larger fixed station transmitters.

The premium subminiature type 5902 is a beam power pentode designed for use as an audio amplifier. It is intended for operation under conditions of severe shock, vibration, high temperature, and high altitude.

Beam power tube - high power sensitivity RCA "Dark Heater" with 12 to 15 volt range.

Sovtek 6A3 power triode tube. Made in Russia.

Triode using the miniature construction. Its low capacitance and high ratio of plate current to transconductance allow use as a high frequency oscillator and mixer at frequencies below ~300 mc or as grounded grid radio frequency amplifier.

High-mu power output triode designed for service in dynamic coupled circuits using a type 76, 6P5GT/G or 6J5GT/G as a driver. Two 6AC5Gs may be used as a zero bias class B amplifier.

High-mu power output triode designed for service in dynamic coupled circuits using a type 76, 6P5GT/G or 6J5GT/G as a driver. Two 6AC5GTs may be used as a zero bias class B amplifier.

Miniature sharp cutoff pentode designed for use where only low plate and screen voltages are available. The 6AJ5 is especially suitable for operation at high frequencies.

Consists of two diodes and a pentode utilizing a common cathode. It is designed for service as a combined detector, AVC rectifier, and pentode amplifier.
