Vacuum Tubes

Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.

Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.

Diode-audio pentode designed especially for service as a combined diode detector and pentode audio amplifier. The diode plate is located at the negative end of the filament.

Screen grid R-F amplifier.

Power amplifier.

Miniature beam power amplifier especially designed for use in the power output stage of a-c/d-c receivers. Its small size and high efficiency make the tube especially useful where space limitation prevent the use of larger types.

Miniature high-mu twin triode each section of which has an individual cathode connection. The tube is especially suited for use as a grounded-grid amplifier or as a frequency converter at frequencies below approximately 300 megacycles.

Beam pentode designed, primarily for use as the horizontal-deflection amplifier in television receivers. The tube exhibits high perveance, high plate current at low plate and screen voltages, and a high ratio of plate to screen current

Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.

General purpose twin triode having two independent units, with all electrodes brought out to separate terminals.

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

Double diode remote cut-off pentode for use as an R.F. or I.F. amplifier.

Miniature, sharp-cutoff pentode designed for intermediate frequency amplifier service in television receivers. Features of the tube include high transconductance and separate base-pin terminals for the cathode and suppressor.

High-vacuum, heater-cathode type of tube designed to indicate visually, by means of a fluorescent target, the effects of change in the controlling voltage. The tube, therefore, is essentially a voltage indicator

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

High-mu triode and sharp-cutoff pentode in the 9 pin miniature construction. It is intended for use in color and black-and-white television receivers.

Power rectifier with low internal voltage drops. It is designed for service in AC operated receivers that require high currents
