New-Old-Stock (NOS) tube. Compactron twin-triode pentode.
New Old Stock (N.O.S.) tube. 25CD6GB is identical to the 6CD6GA except with different heater ratings. Beam power tube, octal base.
New Old-Stock (N.O.S.) tube. The 7189 is a power-amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and high-fidelity amplifiers.
Metal, power-amplifier pentode primarily designed for use in the output stage of video amplifiers. The tube is capable of operating at high plate current levels and exhibits high transconductance and high power sensitivity.
Beam pentode designed for use as a series regulator in high-voltage power supplies.
Special quality tube designed for use as a wide band amplifier, cathode follower, series regulator tube for stabilized DC supply and output tube.
Novar type beam power tube used as a horizontal-deflection amplifier in color and black-and-white television receivers.
Semi-remote cutoff triode in the 7 pin miniature construction. It is designed for use as a VHF and RF amplifier at a B+ of 135 volts.
Neutrode triode tuner in the 7 pin miniature construction. It is designed for use in grounded cathode RF amplifiers, with the neutrode construction providing a lower grid to plate capacitance with consequent ease of neutralization.
Duplex-diode high-mu triode in which separate cathodes are provided for the diode and triode sections. The tube is primarily intended for service as a combined horizontal phase detector and reactance tube in television receivers.
Twin medium-mu triode whose sections are electrically independent except for the common heater. It is designed especially for use in equipment where the operating voltages are obtained from a 12 cell storage battery
12SG7 - Pentode, Semi-Remote Cut-Off, JA
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.
The 10BQ5 is an output pentode designed for application in medium power hi-fi amplifiers. A pair of tubes in class AB, push-pull conventional operation yields an output of up to 17 watts at 4% distortion (without feedback).
Miniature type used as a vertical deflection oscillator or af amplifier and vertical deflection amplifier or af power amplifier in television receivers. Requires miniature 9-contact socket.
Miniature type used in combined vertical-deflection-oscillator and vertical-deflection-amplifier applications in black and white television receivers. Requires miniature 9-contact socket.
Miniature, medium-mu triode intended primarily for use as a vertical-deflection amplifier in television receivers. The tube features high plate current at low plate voltages
Twin diode, medium-mu triode. 7-pin miniature type for use in automobile-radio receivers operating directly from 12-volt storage batteries.
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.
Miniature double didoe, high-mu triode intended for use as a second detector audio amplifier. It is designed for operation where the heater and plate voltages are supplied directly from a 12-volt automotive storage battery.
Power tetrode, medium-mu 9-pin miniature for use in automobile radio receivers operated directly from 12-volt storage batteries.
Combined high-mu voltage amplifier and double-diode detector using the 7-pin miniature construction. It is intended to provide output voltage adequate for full-power output of most beam-power tubes.
Amperex Bugle Boy Brand. Miniature, high-mu, twin triode designed for use as a grounded grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.
