Vacuum Tubes

The 6CW4 isa high-mu triode for use as a grounded-cathode, neutralized RF-amplifier tube in tuners of VHF television and FM receivers.

Full-wave vacuum rectifier. The 5Y4GT is the same as the 5Y4GA except for mechanical design.

Duplex-diode high-mu triode designed for use as a combined detector, automatic-volume-control rectifier and audio amplifier in a-c, a-c/d-c, or automobile receivers.

Medium-mu twin triode 9-pin miniature type, intended for applications where dependable performance under shock and vibration is paramount. The 5814A is a "premium" version of the 12AU7.

Power amplifier.

Miniature high-mu twin triode having separate cathodes. It is designed for service as a relay-control tube in remote tuning units of television receivers.

Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.

Miniature beam pentode primarily designed for use in the audio-frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.

Combines two diodes and a high-mu triode, using a common cathode. It is designed for service as a diode detector, AVC rectifier, and as a high gain resistance coupled amplifier in AC, storage battery, and AC - DC operated receivers.

General purpose filament type triode designed for service in battery operated receivers. With the exception of capacitances its ratings and characteristics are identical with those of the 30.

Heater-cathode type triode designed for use as a detector, amplifier, or oscillator tube in a-c or battery operated equipment.

Combines two low-mu triodes in the lock-in construction. It is designed for use either as a phase inverter or as a voltage amplifier.

42 is a pentode amplifier designed for application in power output stages of receivers

Three-electrode general purpose tube of the heater-cathode type for use as an amplifier and detector in a-c receivers.

Miniature medium-mu twin triode suitable for a wide variety of general-purpose amplifier, oscillator, and multivibrator applications.

The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes. The YJR converts your amp's vacuum tube rectifier to a solid state rectifier, reducing tube sag for a tighter sound and feel.

Filamentary full-wave high-vacuum rectifier designed for use in the power supply of television receivers and other equipments which have high output current requirements.

6C9 is a duo tetrode contained in a 10 pin bulb. It is designed for service as a VHF RF amplifier and a VHF autodyne mixer. Except for heater characteristics, type 17C9 is identical.

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.

Beam power tube for use as a horizontal-deflection amplifier tube in color and black-and-white television receivers.

Triple diode triode for F.M. or FM/AM broadcast receivers and for video and audio signal detection in television receivers.

Beam pentode designed for use as a class "C" RF amplifier, oscillator, or frequency multiplier up to 175 Mc. It can also be used as a modulator or AF amplifier. Type 7558 is designed for fixed station equipment.

Transmitting triode for oscillator applications requiring unusually stable characteristics.

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