Vacuum Tubes

Glass triode power amplifier tube designed particularly for service in the power output stages of storage battery operated or a-c receivers

Cathode type high gain pentagrid converter in the small 9 pin button construction. It is designed for service as a combined local oscillator and mixer at high frequencies, especially in the FM broadcast band.

Isa full-wave high-vacuum rectifier designed for damper service in television deflection circuits. It can also be used in conventional rectifier applications.

Miniature dual-control heptode designed primarily for use as a combined sync separator and sync clipper in television receivers. Each of the two independent control grids exhibits a sharp cutoff characteristic.

Triode intende for use as a grounded grid UHF amplifier for bands IV and V.

The 6DL5 is an output pentode for use in car radio sets.

Combines a triode and a remote cut-off pentode, utilizing a common cathode, in a single bulb.

Cathode type high mu triode designed for use in high gain resistance coupled circuits. A lower amplification factor enables the use of a large signal input both under 250 volt and 100 volt operating conditions.

The 6K6G is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.

Mixer tube designed for service with a separate oscillator as the first detector in superheterodyne receivers. The control grid is of the remote cut-off type which allows the use of AVC and minimizes cross-modulation.

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

Beam power tube for high-fidelity audio-amplifier applications.

Triode-pentode designed primarily for high fidelity audio applications. The pentode section is particularly suited to preamplifier service while the triode section is intended for use as a phase inverter.

Beam-power pentode primarily designed for use in the power output stage of high-fidelity audio-frequency amplifier systems.

Triode, Power Amplifier, United States

General-purpose transmitting beam power tube of the thoriated-tungsten filament type designed for use as an rf power amplifier and oscillator as well as an af power amplifier and modulator.

New Old-Stock (N.O.S.) tube. The 930 is a gas phototube sensitive to red through infrared light.

Groove Tube's Gold Series EL84. The warmest Groove Tube in this family. It remains very buttery, with relatively high power output and very even response. A great replacement for many modern stock amps, overcoming a variety of design issues and limitations in inexpensive tube amps.

Electro-Harmonix KT90 power tube. Made in Russia.
Absolutely the best KT90 ever developed. Wafer base height of 0.34”.

Pentode type amplifier tube with remote cutoff characteristics designed for use as a high frequency amplifier in radio receivers.

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

The type 12SC7 is a twin-triode amplifier designed for use as an audio amplifier or phase inverter. Special shielding arrangement in the base permits operation at a low hum level.

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 pentode designed for use in horizontal deflection circuits of color television receivers.
