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.
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
Miniature full-wave high-vacuum rectifier intended for use in power supplies which have low d-c output-current requirements.
$11.90
Triode using the miniature construction. Its low capacitance and high ratio of plate current to transconductance allow use as a high frequency oscillator and mixer at frequencies below ~300 mc or as grounded grid radio frequency amplifier.
$24.90
Dissimilar double-triode designed for use as a combined vertical-deflection oscillator and amplifier in television receivers.
$19.95
High-mu triode and sharp-cutoff pentode in the 9 pin miniature construction. It is intended for use in color and black-and-white television receivers.
$6.90
Semi-remote cutoff pentode using the lock in construction. IT is designed for use as an RF or IF amplifier.
$6.90
Combines two low-mu triodes in the lock-in construction. It is designed for use either as a phase inverter or as a voltage amplifier.
$15.90
Sharp-cutoff pentode designed for use as a radio-frequency, intermediate frequency, or audio-frequency amplifier in battery operated receivers.
$6.25
Half-wave rectifier in the 7 pin miniature construction. Features of the tube are a 100mA. heater with 20 second warm-up time.
$5.90
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 triode intended primarily for use as a vertical-deflection amplifier in television receivers. The tube features high plate current at low plate voltages
$4.90
The 0B2 is a two-electrode, inert-gas-filled cold cathode miniature tube intended for use as a voltage regulator.
$5.90
Miniature type of medium-mu twin triode intended especially for coverter service in ac/dc FM and AM receivers. In such service, one triode unit may be used as a mixer, and the other as an oscillator.
$14.90
Three-electrode general purpose tube of the heater-cathode type for use as an amplifier and detector in a-c receivers.
$15.25
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 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 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
Pentode amplifier designed for application in power output stages of receivers
$27.90
Heater-cathode type beam power amplifier tube designed for service in the output stage of a-c or battery-operated equipment.
$17.90
Beam pentode designed for use as a class "C" RF amplifier, oscillator, or frequency multiplier up to 175 Mc. It can also be used as a modulator or AF amplifier. Type 7558 is designed for fixed station equipment.
$14.90
Metal, sharp-cutoff pentode for use as a high-gain, audio-frequency amplifier or as a biased detector. The tube is a low-microphonic version of the 6J7 to which it is otherwise identical.
$12.90
Out of Stock
Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.
$19.90
Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. The 50A5 features high power sensitivity and high efficiency when operated at relatively low plate and screen voltages.
$4.90
Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.
