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 medium-mu twin triode designed primarily for use in low-level stages of high-gain audio-frequency amplifiers. The tube is specially designed to exhibit low noise and low microphonic output.
$49.90
Full-wave high-vacuum rectifier for use in power supplies of moderate current requirements. The tube incorporates a unipotential cathode which is internally connected to the filament.
$49.90
The 5U4G is designed for service as a power rectifier in AC operated receivers which require high currents
$49.90
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
Special quality tube designed for use as a wide band amplifier, cathode follower, series regulator tube for stabilized DC supply and output tube.
$49.90
Pentagrid converter designed for service as a combined oscillator and mixer in AC, storage battery, and AC-DC operated receivers
$49.90
Beam power tube with separate grid-no.3 base-pin terminal for "snivets" control. It is designed for horizontal-deflection-amplifier service in Low-B+ black-and-white TV receivers.
$49.90
Transmitting triode for operation at maximum ratings up to 250 Mc.
$48.80
Filamentary twin diode designed for use as a full-wave rectifier in the power supply of television receivers or other equipment which has high direct-current requirements. The 5U4GB may be used a replacement for either the 5U4G or the 5U4GA.
$44.90
Tube having high efficiency and high power sensitivity for use in mobile and stationary equipment. It is rated as an af power amplifier and modulator, a linear rf power amplifier, and a Class C rf power amplifier and oscillator.
$44.90
High-mu twin triode designed primarily for use as an AF voltage amplifier. Featuring a special shielding arrangement to reduce hum, the tube is well suited for low-level audio amplifier service.
$44.90

Magnoval type used as a horizontal-deflection amplifier in color television receivers.
$44.50
Beam pentode designed primarily for use in audio-frequency power amplifier applications where relatively large power outputs are required.
$43.90
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
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
Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. Very low knee voltage, high plate-to-screen ratio, and high peak current capability.
$40.80
Sharp cutoff pentode of the 7 pin miniature type with heater having controlled warm-up time.
$39.90
Beam-power pentode primarily designed for use in the power output stage of high-fidelity audio-frequency amplifier systems.
$39.90
