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.
Beam pentode designed primarily for use in the audio output stage of a-c and storage-battery-operated equipment. It is capable of supplying high power output with high sensitivity, high efficiency, and low third and higher-order harmonic distortion.
$6.90
Remote-cutoff pentode designed for use as a high-gain radio or intermediate-frequency amplifier. Features of the tube include high transconductance, low grid-plate capacitance, and a dual cathode connection

The 6K7GT is an indirectly heated pentode of the vari-mu (remote cut-off) type for use in the RF or IF stages of radio equipment.
$5.90
Miniature high-mu twin triode each section of which has an individual cathode connection - especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits.
$59.95
Single heater-cathode type diode intended for service as the damping diode in the horizontal-deflection circuit of color television receivers. The diffusion bonded cathode practically eliminates one of the major failure mechanisms in damping diodes
$6.90
Miniature, filamentary, sharp-cutoff pentode intended for radio frequency or intermediate frequency amplifier use in battery-operated receivers.
$6.90
Triode-heptode for use in F.M., AM/FM, A.M, and television receivers.
$8.90
Miniature, medium-mu twin triode for use as a radio-frequency amplifier or as a combined oscillator and mixer in VHF television receivers. It my also be used as an audio-frequency amplifier.
$6.90
Filamentary type power output pentode in the miniature construction. It is characterized by economy of filament power and ability to perform well at low plate supply voltages such as encountered in portable equipment.
$4.90
Miniature beam-power amplifier designed primarily for use in the output stage of compact a-c/d-c receivers. The 50B5 features high power sensitivity and is capable of providing a relatively high power output
$3.90
The 6EJ7 is a high transconductance sharp-cutoff pentode in the 9 pin miniature construction.
$4.90
Heater-cathode type high-mu triode designed for service as a high gain audio-frequency amplifier and is especially useful in resistance-coupled amplifier circuits in a-c or battery operated equipment
$4.90
Duplex-diode high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor
$5.90
