Vacuum Tubes
The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
New Old Stock (NOS)
Our new-old-stock tubes were made in the U.S. by the major manufacturers, with several types made in Western Europe or Japan. All NOS tubes are tested and guaranteed.
Transmitting triode for operation at maximum ratings up to 250 Mc.
$48.80
Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.
$6.90
Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.
$4.90
Triode-pentode containing a high-mu triode and a beam pentode. The triode is designed for service as a vertical-deflection oscillator, and the pentode as a vertical-deflection amplifier in television receivers.
$8.90
Power tetrode, medium-mu 9-pin miniature for use in automobile radio receivers operated directly from 12-volt storage batteries.
$5.90
The 12AU6 is a pentode amplifier having a sharp cut-off control characteristic using the miniature construction. With high transconductance, low grid-plate capacitance, it is intended for service as either an RF or AF amplifier.
$5.90
New Old Stock 6W5-G. Full-wave high-vacuum rectifier.
$19.95
Duodecar type used as horizontal-deflection amplifier in television receivers.
$39.90
The 5Z3 is designed for service as a power rectifier in AC operated receivers which require high currents
$24.90
Miniature tube containing a medium-mu triode and a sharp-cutoff pentode. It is especially suited for use as a combined oscillator and mixer at very high frequencies.
$9.90
Frame grid double triode of miniature construction with high transconductance and low noise, designed for service in television receiver VHF cascode RF amplifiers, IF amplifiers, and phase inverter stages.
$23.90
General-purpose power pentode that may be used either in audio output amplifier or video power output amplifier stages of television receivers.
$10.90
Beam power tube for high-fidelity audio-amplifier applications.
$68.25
The 7A8 is an octode converter designed to perform the combined functions of the oscillator and mixer in superheterodyne receivers.
$3.90
Tube containing a single diode and a high-mu triode in one bulb. It is designed for service as a diode detector, AVC rectifier, and as a resistance-coupled amplifier.
$3.90
Heater-cathode type full-wave high-vacuum rectifier doubler tube designed for use in the power supply of a-c or a-c/d-c receivers. Eletrically the 25Z5, 25Z6, and 25Z6GT are identical.
$5.90
Miniature sharp-cutoff pentode for use as a wide-band, high-frequency amplifier. It is also useful in video and audio amplifiers, oscillators, mixers, frequency multipliers, and cathode followers.
$4.90
Miniature duplex-diode, high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor
$5.90
General purpose triode designed for service as an oscillator, detector, or amplifier. It is similar in characteristics to the 6C6, 6J7, and 57 with triode connection.
$39.90
Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. It is characterized by having a very low knee with a very high peak current of over an ampere.
