Beam power pentode primarily intended for use as an audio frequency power amplifier. It is particularly useful in applications where the available supply voltage is relatively low.

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.

The type 3Q4 is a miniature type power-amplifier pentode designed for use in the output stage of battery operated equipment.

Heater-cathode type beam tube of miniature construction designed primarily to form the combined operations of the limiter, discriminator, and audio-voltage amplifier in FM and intercarrier television receivers.

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.

Medium-mu triode in the 7-pin miniature construction. It is designed for local oscillator service in television receivers which operate in the UHF region, internal lead inductance is reduced by employing double connections to the plate and grid.

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.

Power pentode of the glass octal type. This tube is suitable for all applications which require peak powers of up to 11 watts from a single tube or up to 100 watts from two tubes in the normal push-pull arrangement

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

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.

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

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

High-perveance beam power amplifier designed as a direct retrofit for the 6AR6 or 6098 in aircraft, military, and industrial applications

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.

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

Beam power tube for horizontal deflection amplifier service in black-and-white TV receivers.

Miniature type used in combined vertical-deflection-oscillator and vertical-deflection-amplifier applications in black and white television receivers. Requires miniature 9-contact socket.

Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. It is characterized by having a very low knee with a very high peak current of over an ampere.

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.

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.

Dual Triode, Gold Pins

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.

Triple grid sharp cut-off amplifier. It is designed for service in high gain RF and IF amplifier applications and for limited service in FM receivers. The double cathode connection is useful in reducing cathode circuit coupling.

High vacuum full wave rectifying tube.
