The 7534 is designed to provide low hum, non-microphonic operation through the incorporation of a helical wound heater and rigid mounting of the internal components. The 7534 is otherwise similar to, and a replacement for the 6AU6.

Dissimilar double triode utilizing the 9T9 bulb and pin configuration. The tube is designed to serve as a combined vertical deflection oscillator and amplifier.

Double triode with high transconductance and low noise for use as a cascode amplifier in tuners for television receivers.

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.

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.

Duodecar type used as a horizontal-amplifier tube in color and black-and-white television receivers.

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

Medium-mu twin triode of the 9 pin miniature type intended for use in the matrixing circuits of color television receivers. It can also be used in phase-inverter, multivibrator, and general-purpose amplifier applications

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.

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.

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

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.

Compactron beam-power pentode designed for use in the horizontal deflection amplifier in television receivers. A separate connection is provided for the beam plates to minimize "snivets".

High-transconductance twin triode designed for use in VHF circuits as a cathode follower, grounded-grid amplifier, or frequency converter. Except for heater voltage and current ratings, it is identical to the 7F8.

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.

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

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.

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.

Medium-mu triode in the 9 pin miniature construction. It is particularly suited for use in general-purpose amplifier and phase-inverter circuits as well as for the multi-vibrator and oscillator applications.

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

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

Transmitting beam power amplifier.

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.

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.
