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 each section of which as a separate cathode connection. The tube is suited for use in a wide variety of general-purpose amplifier and mixer circuits as well as numerous multi-vibrator and oscillator applications.
$4.90
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
$6.90
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
Sharp cutoff pentode intended for critical industrial applications where 10,000 hour life, extreme uniformity, rigid construction, and exceptional stability are paramount.
$19.90
Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.
$4.90
Miniature pentagrid converter designed for use as a combined mixer and oscillator in superheterodyne circuits.
$4.90
Miniature high-mu twin triode each section of which as an individual cathode connection suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, andindustrial-control circuits where high voltage gain is desired.
$49.95
Heater-cathode type transmitting beam power amplifier in the 9 pin miniature construction. It is intended for use in compact, low-power mobile transmitters and in the low-power stages of larger fixed station transmitters.

Originally: $12.90
Medium-mu twin triode 9-pin miniature type, intended for applications where dependable performance under shock and vibration is paramount. The 5814A is a "premium" version of the 12AU7.
$16.90
9-pin miniature triode with an indirectly heated cathode. It is intended primarily for grounded grid operation in the input stage of broad band amplifiers.
$22.45
Sharp-cutoff pentode of the 9-pin miniature type intended for use as an audio amplifier in applications requiring reduced microphonics, leakage noise, and hum.
$12.90
The 5881 is the electrical equivalent to types 6L6 and 6L6GC except that the plate and screen dissipation ratings have been increased approximately 20 percent.
$59.90
The premium subminiature type 5902 is a beam power pentode designed for use as an audio amplifier. It is intended for operation under conditions of severe shock, vibration, high temperature, and high altitude.
$9.90
Rugged full-wave filamentary type rectifier designed for use in applications requiring resistance to shock or vibration.
$34.90
Rugged beam amplifier tube designed for use in mobile transmitters or amplifiers which may be submitted to shock or vibration.
$21.55
Miniature, medium-mu twin triode for use as a frequency divider in computer applications.
$9.90
Miniature twin-triode primarily designed for service in computer applications. Each triode section features a high zero-bias plate current, a sharp-cutoff characteristic, and a separate cathode connection.
$4.90
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
