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.
Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier

42 is a pentode amplifier designed for application in power output stages of receivers
Starting at $15.80
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
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
$6.90
Miniature double diode high mu triode designed for service as a combined first audio amplifier, detector, and AVC tube in radio receivers. However, the 6AQ6 employs a 150 mA heter.
$3.90
Triple grid general purpose detector amplifier. With the exception of capacitance, its electrical characteristics are identical with those of the 6J7G and 6J7GT.
$8.90
Miniature beam power pentode designed for service as a general purpose audio power amplifier or vertical deflection amplifier in television receiver sweep circuits
$6.90
Compactron dissimilar double triode designed for used as a combined vertical-deflection oscillator and amplifier in television receivers.
$4.90
Combined triode and beam pentode especially intended for use in vertical output stage, particularly 110 degree picture tubes. Special attention has been paid to properties important for this application, such as microphonism and linearity.
$4.45
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
Combines two diodes and a high-mu triode in a single envelope, using a common cathode. It is designed for service as a diode detector, AVC rectifier, and as a high gain resistance coupled amplifier
$7.85
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
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
Three-electrode general purpose tube of the heater-cathode type for use as an amplifier and detector in a-c receivers.
$15.25
Low-mu triode designed for use as the vertical deflection amplifier in television receivers.
$12.90
Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.
$5.90
