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.
Vacuum Tube - 2050, Thyratron, ST Shape
Xenon filled four electrode thyratron with negative control characteristic. This tube is designed for relay applications for grid-controlled rectifier service.
$19.90
Vacuum Tube - 27, Triode, ST Glass
Three-electrode general purpose tube of the heater-cathode type for use as an amplifier and detector in a-c receivers.
$15.25
Vacuum Tube - 6AC10, Triple Triode
Compactron containing three high-mu triodes. It is designed for use primarily as a color-difference amplifier in color television receivers.
$7.90
Vacuum Tube - 6SK7GT, Pentode, Remote Cut-Off, RF
Remote-cutoff pentode. It is designed for use as a high-gain radio-frequency or intermediate-frequency amplifier in a radio receiver.
$5.90
Vacuum Tube - 12SK7GT, Pentode, Remote Cut-Off, RF
Single ended cathode type super control pentode primarily designed for amplifier service in radio or intermediate frequency circuits. In properly designed superheterodyne circuits it may also be used as a mixer tube.
$6.90
Vacuum Tube - 35Y4, Rectifier, Half Wave
Half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. The heater is tapped to permit operation of a panel lamp.
$8.90
Vacuum Tube - 6D6, Pentode, Remote Cut-Off
Triple grid variable MU amplifier. It is suitable for use with AVC in RF and IF amplifiers as it minimizes cross modulation
$6.90
Vacuum Tube - 6J5GT, Triode, Medium MU
General-purpose triode designed for use as a detector, amplifier, or oscillator. Features include a relatively high transconductance and a medium amplification factor.
$22.95
Vacuum Tube - 6JE6C / 6LQ6, Beam Power Amplifier
Beam pentode featuring Novar construction with a special plate fin. The fin provides improved heat distribution and a greater plate dissipation capability. This in turn increases reliability under rated conditions.
$69.90
Vacuum Tube - 6K11 / 6Q11, Triode, Triple
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
Vacuum Tube - 6Y6GT, Beam Power Amplifier
Beam power pentode primarily intended for use as an audio frequency power amplifier. It is particularly useful in applications where the available supply voltage is relatively low.
$5.90
Vacuum Tube - 7F7, Dual Triode, HI-MU
Twin high-mu triode using the lock-in construction. It is designed for use as a voltage amplifier in resistance coupled cascade or phase inverter service.
$9.90
$23.95
Vacuum Tube - 14AF7 / XXD, Dual Triode, Medium MU
Medium-mu twin triode designed for use as a voltage amplifier or oscillator.
$7.90
$27.55
Vacuum Tube - 5672 / DL69, Pentode
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
$6.90
Vacuum Tube - 6AW8A, Triode, Pentode
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.
$4.90
Vacuum Tube - 6DC6, Pentode, Semi-Remote Cut-Off
Semi-remote cutoff pentode. It is designed for service in the IF stages of color and monochrome television receivers and may be used in the tuners of such sets as an AF amplifier.
$7.90
Vacuum Tube - 6E5, Indicator, Tubular Glass
High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.
$33.60
Vacuum Tube - 75, Dual Diode, Triode, ST Glass
Heater-cathode type duplex-diode high-mu triode designed for use as a combined detector, audio-frequency amplifier and automatic-volume-control tube
$27.45
Vacuum Tube - 7F8, Dual Triode
Twin triode designed for use as a grounded-grid radio-frequency amplifier or as a frequency converter at frequencies up to 300 megacycles.
$11.90
Vacuum Tube - 807, Beam Power Amplifier
Beam pentode for power amplifier, oscillator, and modulator applications.
$24.70
Vacuum Tube - 50A5, Tetrode, Beam Power
Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. The 50A5 features high power sensitivity and high efficiency when operated at relatively low plate and screen voltages.
$4.90
Vacuum Tube - 5651A, Voltage Reference
Voltage-reference tube, 7-pin miniature, glow-discharge type. Especially useful as a voltage reference tube in DC power supplies.
