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.
Dissimilar double-triode designed for use as a combined vertical deflection oscillator and amplifier in television receivers
$6.90
Heather cathode type tube consisting of two diodes and a triode in a single bulb. It is designed for use as a combined detector, amplifier, and automatic volume control.
$7.90
Miniature high-mu twin triode especially suited for use in resistance-coupled voltage amplifier, phase inverters, multivibrators, and other applications in which high voltage gain is desired.
$49.90
Consists of two dynamically coupled triodes and is designed for service in the power output stage of AC and storage battery operated receivers. All necessary biases are supplied internally
$24.70
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
Converter tube designed for stable operation over an extended frequency range. It consists of a heptode mixer and a triode oscillator, having a common cathode. The injector grid of the heptode is internally connected to the triode grid.
$18.90
Cathode type high mu triode designed for use in high gain resistance coupled circuits. A lower amplification factor enables the use of a large signal input both under 250 volt and 100 volt operating conditions.

Rugged high mu twin triode designed for service as a resistance coupled amplifier or phase inverter in applications requiring resistance to shock and vibrations.
$40.95
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
$4.90
High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Except for the use of a T-12 glass envelope, the 6AS7GA is identical to the 6AS7G.
$11.90
Medium mu triode and a semi-remote cutoff pentode in the 9 pin miniature construction. It is intended for general purpose applications in both monochrome and color television receivers.
$12.90
Miniature duplex-diode medium-mu triode in which separate cathode and plate connections are provided for each diode section. The tube is intended primarily as a combined synchronous detector and chrominance amplifier in color television receivers.
$6.90
High-transconductance twin triode designed primarily for use as a combined vertical deflection amplifier and vertical oscillator in television receivers.
$19.90
General purpose triode designed for service as an oscillator, detector, or amplifier
$28.50
The 6SS7GT is an RF pentode which as remote plate current cutoff. It is suitable for operating with AVC in Rf and IF amplifiers. The use of this tube will reduce cross modulation effects.
$7.90
Duodecar type tube used in audio-frequency circuits. The triode unit is used as a voltage amplifier; the pentode unit is used as a power amplifier.
$19.90
Filament type power amplifier having low plate resistance.
$59.60
Filament type triode designed for use in the amplifier stages of a-c operated receivers.
$31.65
Heater-cathode type duplex-diode high-mu triode designed for use as a combined detector, audio-frequency amplifier and automatic-volume-control tube. Except for heater rating the 2A6 and 75 are identical.
$7.90
Miniature, medium-mu twin triode for service in electronic computers. The electrical characteristics are essentially equivalent to those of the 5844.
$4.45
Miniature high-mu twin triode suitable for use as a grounded-grid amplifier or as a frequency converter at frequencies below approximately 300 megacycles. Its electrical characteristics are essentially equivalent to those of the 12AT7.
$10.90
