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.
The 0C3-A is a two-element gas filled, cold cathode voltage regulator. It is designed to provide a regulated output of approximately 105 volts.
$6.90
Miniature space-charge-grid tetrode intended for use as a driver for the transistor power-output stage of automobile radio receivers.
$8.90
Low-voltage, low-current drain, battery type triode. It is designed for service as an oscillator, detector, or amplifier in receivers using 90 volts "B" battery and a single dry cell "A" battery.
$7.90
High vacuum rectifier intended for use in full-wave applications. The tube incorporates an indirectly heated cathode which is internally connected to the heater
$29.90
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
Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.
$3.55
Compactron, containing three high-mu triodes with separate pin connections for all three cathodes, grids, and plates. It is especially designed for use as an oscillator-mixer, grounded-grid amplifier, and automatic frequency control service.
$22.95
Double triode with dissimilar section in the 9 pin miniature construction. Section #1 has a high mu and is intended for use as a vertical deflection oscillator. Section #2 has a low mu and is designed for use as a vertical deflection amplifier
$6.90
Miniature, high-mu, twin triode primarily designed for use in low-level stages of high-gain audio frequency amplifiers.
$34.90
Heater-cathode type beam power amplifier tube designed for service in the output stage of a-c or battery-operated equipment.
$17.90
Beam power tube of the 9-pin miniature type designed for use as the output amplifier in automobile radio receivers operating from a 12-volt storage battery. The 12AB5 can provide high power output.
$5.90
Medium-mu twin triode intended for service in radio and television receivers or in audio amplifiers. The tube is suitable for use in a variety of stages, such as general-purpose amplifier, phase inverter, oscillator, or multivibrator.
$22.90
Miniature medium-mu twin triode designed primarily for use in low-level stages of high-gain audio-frequency amplifiers. The tube is specially designed to exhibit low noise and low microphonic output.
$49.90
Low-voltage, low-current drain, battery type power pentode. It is designed for service with 90 volts of "B" battery and a single dry cell "A" battery.
$11.90
Triple grid variable MU amplifier. It is suitable for use with AVC in RF and IF amplifiers as it minimizes cross modulation
$6.90
Diode and a remote cutoff pentode with a common cathode of the 9 pin miniature type especially designed for use as combined IF amplifier and AM detector tubes in AM and AM/FM broadcast receivers.
$4.90
Pentode amplifier designed for application in power output stages of receivers
$27.90
Compactron device containing two high-mu triodes and one medium-mu triode. Features of the tube include separate pin connections for all three cathodes, grids, and plates; an internal shield between sections 1 and 3.
$43.90
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.
$5.90
Out of Stock
General purpose medium-mu triode. It is useful for service as an oscillator or audio-frequency amplifier.
$5.90
