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.
Sharp cut-off amplifier pentode designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. The 6SH7 is not recommended for use as a high-gain audio amplifier because undesirable hum may be encountered.
$4.90
The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.
$23.95
Miniature low-mu triode designed primarily for service as a vertical-deflection amplifier in television receivers. The tube features high plate current at relatively low plate voltages
$5.90
The 5R4GY is designed for rectifier use in equipment requiring a high peak inverse voltage rating. Satisfactory operation of this tube type under conditions falling within area 1 on curve no 1 may be obtained without filament preheating.
$24.90
Full-wave rectifier of the heater-cathode type intended for use in AC operated and automobile receivers. Because of its heater-cathode construction it has the same heating time as that of other heater-cathode types in the receiver.
$5.90
Heater-cathode type beam tube of miniature construction designed primarily to form the combined operations of the limiter, discriminator, and audio-voltage amplifier in FM and intercarrier television receivers.

Originally: $4.90
Frame grid double triode of miniature construction with high transconductance and low noise, designed for service in television receiver VHF cascode RF amplifiers, IF amplifiers, and phase inverter stages.
$23.90
Diode and a remote cutoff pentode with a common cathode of the 9 pin miniature type especially designed for use as combined IF amplifier and AM detector tubes in AM and AM/FM broadcast receivers.
$4.90
Beam pentode featuring Novar construction with a special plate fin. The fin provides improved heat distribution and a greater plate dissipation capability. This in turn increases reliability under rated conditions.
$69.90
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
Beam pentode for power amplifier, oscillator, and modulator applications.
$24.70
Contains two independent medium-mu triodes with unipotential cathodes in the 9-pin miniature construction.
$13.90
Half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. The heater is tapped to permit operation of a panel lamp.
$8.90
Voltage-reference tube, 7-pin miniature, glow-discharge type. Especially useful as a voltage reference tube in DC power supplies.
$4.90
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
$6.90
General purpose high-mu triode. It is designed for service as a high gain resistance coupled amplifier in AC and AC - DC operated receivers.
$6.90
Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier
$4.90
Beam-power pentode in the 12 pin compactron construction. It is designed primarily for use as the horizontal-deflection amplifier in color television receivers.
$24.90
Heater-cathode type duplex-diode high-mu triode designed for use as a combined detector, audio-frequency amplifier and automatic-volume-control tube
$27.45
Twin high-mu triode using the lock-in construction. It is designed for use as a voltage amplifier in resistance coupled cascade or phase inverter service.
$9.90
Heater-cathode type diode pentode tube designed for use as a detector and intermediate-frequency or audio-frequency amplifier. Except for heater rating the 6SF7 and 12SF7 are identical.
$6.90
Medium-mu twin triode designed for use as a voltage amplifier or oscillator.
$7.90
Low-voltage, low-current drain, battery type triode. It is designed for service as an oscillator, detector, or amplifier in receivers using 90 volts "B" battery and a single dry cell "A" battery.
