# 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.
Vacuum Tube - 12AX7-A, Triode, Dual, High MU
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.

Vacuum Tube - 6SG7, Pentode, Semi Remote
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
$6.90 Vacuum Tube - 12SN7GT-A-B, Triode, Dual, Medium MU Medium-mu twin triode suitable for use in a wide variety of general purpose amplifier and phase-inverter applications. Except for heater characteristics and ratings, the 12SN7GA-B is identical to the 6SN7GTB$6.90
Vacuum Tube - 25L6GT / 25W6, Beam Power Amplifier, Tubular Glass
Beam pentode designed for use in the audio-frequency power output stage of radio and television receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.
$6.90 Vacuum Tube - 50L6GT, Beam Power Amplifier The 50L6GT is designed for service in the output stage of ac/dc receivers. It delivers a high power output with high power sensitivity from low supply voltages.$9.90
Vacuum Tube - 6CS7, Triode, Dissimilar Double
Miniature double triode having dissimilar sections. Section no. 1 is intended for operations as a vertical deflection oscillator and section no. 2 as a vertical deflection amplifier.
$4.90 Vacuum Tube - 6HF5, Beam Power Amplifier 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
Vacuum Tube - KT88, Electro-Harmonix
Electro-Harmonix KT88 Vacuum Tube High power kinkless-tetrode for use in amplifiers such as the Marshall Major. This tube is a favorite of audiophiles. Can be used in place of 6550 for a more "round" bass signature.
Starting at $67.60 Vacuum Tube - 6BN8, Dual Diode, Triode Miniature, high mu triode, double diode intended for application in color and monochrome television receivers. Separate cathode connections for each section and controlled heater warm-up time to insure dependable operation in series string receivers$8.95
Vacuum Tube - 6CL6, Pentode, Power
Miniature power pentode designed primarily for use as the video output amplifier in television receivers. The tube exhibits high transconductance, high power sensitivity, and low interelectrode capacitances.
$7.90 Vacuum Tube - 6Y6GT, Beam Power Amplifier Beam power pentode primarily intended for use as an audio frequency power amplifier. It is particularly useful in applications where the available supply voltage is relatively low.$5.90
Vacuum Tube - EL844, JJ Electronics
The JJ Electronic EL844 is a variation on the classic tube which reduces the overall headroom by 25%. With the reduced power, hitting that rich distortion that the EL84 is notorious for is more manageable. This tube will hit full saturated power tube sounds without having to crank the amps volume as high which makes them a great choice for recording as well as home / bedroom use.
Starting at $18.45 Partially Out of Stock Vacuum Tube - KT88, JJ Electronics, Blue Glass Blue glass envelope. A sonically faithful reproduction of the original tubes with a robust construction encased in a thick glass envelope. The JJ KT88 delivers a powerful 42 Watts with plenty of headroom to spare. This tube has a tone that is warm and lively with a detailed and balance response. Starting at$69.95
Vacuum Tube - 1S5 / DAF91, Diode, Sharp Cut-Off Pentode
Miniature tube containing a diode and a sharp-cutoff pentode. It is designed for use as a combined detector and audio-frequency voltage amplifier in compact battery-powered equipment.
$3.55 Vacuum Tube - 3C24 / 24G, Triode Medium-mu triode - modulator, oscillator, amplifier.$19.90

Vacuum Tube - 6BJ6 / E99F, Pentode, Remote Cut-Off
Miniature, remote-cutoff pentode designed primarily for use as a high-gain radio-frequency or intermediate-frequency amplifier. Features include low grid-plate capacitance, relatively high transconductance, and low heater current.
$6.90 Vacuum Tube - 6BQ7A / 6BZ7, Dual Triode Miniature, medium-mu twin triode primarily designed for use as a cascode, radio-frequency amplifier in very high frequency television tuners. In this application, its performance is characterized by high gain and low noise figure.$3.55
Vacuum Tube - 12AD6 / 12AG6, Heptode
Miniature heptode primarily intended to perform the combined functions of mixer and oscillator in automobile radio receivers. Specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.
