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.
Voltage Regulator, Diode, Glow-Discharge type.
$6.90
9-pin miniature type high-mu twin triode, with heater having controlled warm-up time.
$8.90
The 6CW5 is an A.F. output pentode in the 9 pin miniature construction. It is intended for use in single-ended push-pull output stages.
$6.90
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
Medium-mu triode using the lock-in construction. It is designed for use as an oscillator, detector, or amplifier. It is characterized by moderately high transconductance. It is particularly applicable for service in the higher frequencies.
$9.90
Miniature pentagrid-converter designed for use as a combined mixer and oscillator in superheterodyne circuits. Because of its small size and high operating efficiency, the 1R5 is especially adapted for compact, battery-operated equipment.
$5.90
The 5Z4 is designed for service as a power rectifier in AC operated receivers.
$8.90
Miniature, remote-cutoff pentode designed primarily for use as a high-gain radio-frequency or intermediate-frequency amplifier. Features include low grid-plate capacitance, relatively high transconductance, and low heater current.
$6.90
Miniature, medium-mu twin triode primarily designed for use as a cascode, radio-frequency amplifier in very high frequency television tuners. In this application, its performance is characterized by high gain and low noise figure.
$3.55
Miniature power pentode designed primarily for use as the video output amplifier in television receivers. The tube exhibits high transconductance, high power sensitivity, and low interelectrode capacitances.
$7.90
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.
$15.90
Medium-mu twin triode suitable for use in a wide variety of general-purpose amplifier and phase-inverter applications. It is also especially useful as a blocking oscillator, multivibrator, or vertical deflection amplifier in television receivers.
$22.95
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
Low voltage, low current drain battery type beam power output tube. It is designed for services with 90 volts of "B" battery and a single dry cell "A" battery.
$4.90
Miniature tube containing a diode and a sharp-cutoff pentode. It is designed for use as a combined detector and audio-frequency voltage amplifier in compact battery-powered equipment.
$3.55
General purpose medium-mu double triode using the 9-pin button all-glass construction. The tube is characterized by high perveance and high emission capabilities.
$19.90
The 6BM8 contains both a power pentode and triode. It has a pentode plate dissipation rating of 7 watts with convection cooling.
$29.95
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 also be used in a biased detector, oscillator phase inverter or class A amplifier
$7.90
Heater-cathode type beam-power amplifier tube designed for use in the audio-output stage of ac or ac/dc receivers.
$4.90
Combined high-mu voltage amplifier and double-diode detector using the 7-pin miniature construction. It is intended to provide output voltage adequate for full-power output of most beam-power tubes.
$6.90
Miniature power pentode designed primarily for use as the video output amplifier in television receivers. Like the 12BY7, it features high transconductance, high power sensitivity, and low interelectrode capacitances.
$13.90
Filament type double grid power amplifier tube. It is especially designed for class B operation to give a large amount of undistorted power output.
$34.75
Remote-cutoff pentode. It is designed for use as a high-gain radio-frequency or intermediate-frequency amplifier in a radio receiver.
$5.90
The 6SS7 is an RF pentode which as remote plate current cutoff. It is suitable for operating with AVC in Rf and IF amplifiers. The use of this tube will reduce cross modulation effects.
