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.
General purpose filament type triode designed for service in battery operated receivers. With the exception of capacitances, its ratings and characteristics are identical with those of the 1H4G.
$19.90
The 41 is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.
$19.90
Glass octal type for industrial and military applications.

Duodecar type used as horizontal-deflection amplifier in color and black-and-white television receivers.
$19.90
Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.
$19.90
Heater-cathode type twin triode designed for use as a class B power amplifier in the output stage of a-c or battery operated equipment. It may be used in other applications such as a biased detector, oscillator phase inverter or class A amplifier
$19.60
Out of Stock
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
Heater-cathode type beam power amplifier tube designed for service in the output stage of a-c or battery-operated equipment.
$17.90
New-Old-Stock (NOS) tube 5R4GA - Rectifier, Full Wave
$17.90
Out of Stock
Beam power amplifier designed specifically for applications requiring relatively high peak plate currents at negative grid potentials. It is constructed to withstand relatively high plate potentials.
$17.75
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
Starting at $17.60
Full-wave vacuum rectifier. The 5Y4GT is the same as the 5Y4GA except for mechanical design.
$16.90
Duplex-diode high-mu triode designed for use as a combined detector, automatic-volume-control rectifier and audio amplifier in a-c, a-c/d-c, or automobile receivers.
$16.90
The 6CW4 isa high-mu triode for use as a grounded-cathode, neutralized RF-amplifier tube in tuners of VHF television and FM receivers.
$16.90
Medium-mu twin triode 9-pin miniature type, intended for applications where dependable performance under shock and vibration is paramount. The 5814A is a "premium" version of the 12AU7.
$16.90
Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.
$15.90
Miniature high-mu twin triode having separate cathodes. It is designed for service as a relay-control tube in remote tuning units of television receivers.
$15.90
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.
$15.90
Miniature beam pentode primarily designed for use in the audio-frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.
