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.
Miniature, filamentary, sharp-cutoff pentode intended for radio frequency or intermediate frequency amplifier use in battery-operated receivers.
$6.90
Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.
$6.90
Glass-type half-wave high-vacuum rectifier with an indirectly heated cathode. It is especially designed for use in a-c/d-c and automobile receivers.
$7.90
Filament type triode power amplifier. It is designed for service in the output stage of audio amplifiers where high output and low harmonic distortion is desired.
$179.90
Type 2A5 is a pentode amplifier designed for application in power output stages of receivers. With the exception of heater ratings, their electrical characteristics are identical.
$21.90
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
Are pentagrid converters designed for service as oscillators and mixers in ac operated and ac-dc operated receivers. With the exception of heater ratings, they have identical rating and electrical characteristics.
$9.90
Miniature, four-electrode, inert-gas-filled thyratron with negative control characteristics of the tube include a high control ratio essentially independent of temperature over a wide range low grid-anode capacitance and very low grid current.
$6.90
The 3A4 is designed for use in compact, lightweight, portable equipment. The relatively large filament employed in the 3A4 enables it to supply the high peak currents required in RF power applications.
$5.90
The 3A5 is intended for use in high frequency applications. The relatively large filament employed in the 3A5 enables it to supply the high peak currents required in RF power applications.
$5.90

Filament type power-amplifier pentode tube designed for use in the output stage of battery operated equipment.
$4.90
Filamentary type power output pentode in the miniature construction. It is characterized by economy of filament power and ability to perform well at low plate supply voltages such as encountered in portable equipment.
$4.90
Miniature power amplifier pentode designed for use in the power output stage of compact, battery operated equipment. It is particularly useful in three-way portable receivers which employ 90-volta batteries.
$8.90
Beam type aligned grid power amplifier. It has a unipotential oxide-coated cathode, a hard glass nonex bulb, and a glass base with short tungsten leads. The tube has a heater designed to operate from a 6.3 volt supply.
$71.95
Heater-cathode twin diode designed for full-wave rectifier operation. High output current and small size make this tube especially suitable for compact amplifier designs.
Starting at $52.90
