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.
Power-amplifier tube of the all-metal type for use in the output stage of transformerless (ac/dc) radio receivers, especially those designed to have ample reserve of power-delivering bilities.

Originally: $9.95
Filament-type high-vacuum full-wave rectifier designed for service in power supplies of moderate current requirements. The electrical characteristics of the 5AZ4 are equivalent to those of the 5Y3GT.
$6.90
Miniature high-mu twin triode each section of which has an individual cathode connection. The tube is especially suited for use as a grounded-grid amplifier or as a frequency converter at frequencies below approximately 300 megacycles.
$23.95
Beam pentode designed, primarily for use as the horizontal-deflection amplifier in television receivers. The tube exhibits high perveance, high plate current at low plate and screen voltages, and a high ratio of plate to screen current
$7.90
Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.
$4.90
General purpose twin triode having two independent units, with all electrodes brought out to separate terminals.

Double diode remote cut-off pentode for use as an R.F. or I.F. amplifier.
$6.90
Medium-mu twin triode of the 9 pin miniature type intended for use in the matrixing circuits of color television receivers. It can also be used in phase-inverter, multivibrator, and general-purpose amplifier applications
$7.90
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
Triode-pentode designed primarily for high fidelity audio applications. The pentode section is particularly suited to preamplifier service while the triode section is intended for use as a phase inverter.
$69.90
Power rectifier with low internal voltage drops. It is designed for service in AC operated receivers that require high currents
$25.60
Combines two independent diode units in the 7-pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.
$7.90

Miniature pentagrid converter designed for use as a combined mixer and oscillator in superheterodyne circuits.
$4.90
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 beam amplifier tube designed for use in mobile transmitters or amplifiers which may be submitted to shock or vibration.
$21.55
Tube having high efficiency and high power sensitivity for use in mobile and stationary equipment. It is rated as an af power amplifier and modulator, a linear rf power amplifier, and a Class C rf power amplifier and oscillator.
$44.90
Miniature beam-power pentode designed for use as an audio-frequency power amplifier.
$14.90
High perveance triode for use as a vertical deflection amplifier in television receivers.
$19.90
Triode intende for use as a grounded grid UHF amplifier for bands IV and V.
$7.90
High-perveance beam power pentode designed for use as a horizontal deflection amplifier tube in high efficiency deflection circuits of television receivers.
$9.90
High-vacuum, heater-cathode type of tube designed to indicate visually, by means of a fluorescent target, the effects of change in the controlling voltage. The tube, therefore, is essentially a voltage indicator
