Vacuum Tubes

High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.

General purpose high-mu triode. It is designed for service as a high gain resistance coupled amplifier in AC and AC - DC operated receivers.

Beam pentode featuring Novar construction with a special plate fin. The fin provides improved heat distribution and a greater plate dissipation capability. This in turn increases reliability under rated conditions.

Heater-cathode type pentode amplifier tube with remote cut-off characteristics and is designed for use as a radio frequency or intermediate frequency amplifier in a-c or battery operated equipment

Beam pentode for power amplifier, oscillator, and modulator applications.

Power amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and in high fidelity amplifiers.

Super-premium Octal Beam Tetrode, impervious to overload when used at parameters found in existing 6550/KT88/KT90 circuits. Plate dissipation of 60 watts and higher current handling capacity has allowed the design of new amplifiers which are unique, extremely powerful and stable.

Contains two independent medium-mu triodes with unipotential cathodes in the 9-pin miniature construction.

Beam Power Amplifier

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

Miniature, high mu triode, double diode intended for application in color and monochrome television receivers. Separate cathode connections for each section and controlled heater warm-up time to insure dependable operation in series string receivers

Beam-power pentode in the 12 pin compactron construction. It is designed primarily for use as the horizontal-deflection amplifier in color television receivers.

Sharp cut-off amplifier pentode designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. The 6SH7 is not recommended for use as a high-gain audio amplifier because undesirable hum may be encountered.

Twin high-mu triode using the lock-in construction. It is designed for use as a voltage amplifier in resistance coupled cascade or phase inverter service.

Sovtek 12AX7WC dual triode preamp tube. Made in Russia.

Heater-cathode type diode pentode tube designed for use as a detector and intermediate-frequency or audio-frequency amplifier. Except for heater rating the 6SF7 and 12SF7 are identical.

Medium-mu twin triode designed for use as a voltage amplifier or oscillator.

This triode has a full 40 Watts of power. The robust build of the JJ 300B offers high reliability in a classy package. Each tube comes with a factory certification with sets dual matched for anode current and gain. The JJ 300B has a balanced and detailed sound with a wide frequency response.

Voltage-reference tube, 7-pin miniature, glow-discharge type. Especially useful as a voltage reference tube in DC power supplies.

The 6100 / 6C4WA is a heater-cathode type medium-mu triode of miniature construction, suitable for use as a class C amplifier and oscillator. This type is characterized by long life and stable performance.

Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier
