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.

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
T-78 Vacuum Tube - 78, Pentode, Remote Cut-Off
Heater-cathode type pentode amplifier tube with remote cut-off characteristics and is designed for use as a radio frequency or intermediate frequency amplifier in a-c or battery operated equipment
$7.90
T-1A5GT Vacuum Tube - 1A5GT, Pentode, Power Amplifier
Filament type power-amplifier pentode designed for use in the output stage of low drain battery operated equipment. The 1A5GT may be operated singly or in push-pull combination.
$4.90
T-2050 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
T-50X6 Vacuum Tube - 50X6, Rectifier, Full Wave
Combines two independent diodes in the lock-in construction permitting the tube to be used as a power rectifier in either half-wave, full-wave, or voltage doubler applications.
$4.90
T-6AS7GA Vacuum Tube - 6AS7GA, Dual Triode, Low MU
High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Except for the use of a T-12 glass envelope, the 6AS7GA is identical to the 6AS7G.
$11.90
