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 - 6AH4GT, Triode
High perveance triode for use as a vertical deflection amplifier in television receivers.
$19.90
Vacuum Tube - 6AH6, Pentode, Sharp Cut-Off
Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.
$3.55
Vacuum Tube - 6AJ5, Pentode, Sharp Cut-Off
Miniature sharp cutoff pentode designed for use where only low plate and screen voltages are available. The 6AJ5 is especially suitable for operation at high frequencies.
$6.25
Vacuum Tube - 6AJ8 / ECH81, Triode, Heptode
Triode-heptode for use in F.M., AM/FM, A.M, and television receivers.
$8.90
Vacuum Tube - 6AK5 / EF95, Pentode, Sharp Cut-Off
Miniature types used as RF or IF amplifiers especially in high-frequency wide-band applications at frequencies up to 400MHz.
$4.90
Vacuum Tube - 6AK6, Pentode
Heater-cathode type of tube intended for use in compact, light-weight equipment. Because of its small size, the 6AK6 can be used singly or in push-pull to effect a more compact design of power-line receivers.
$4.90
Vacuum Tube - 6AK8 / EABC80, Dual Diode, Triode
Triple diode triode for F.M. or FM/AM broadcast receivers and for video and audio signal detection in television receivers.
$14.90
Vacuum Tube - 6AL5 / 6EB5, Dual Diode
The 6AL5 combines two independent diode units in the 7 pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.
$4.90
Vacuum Tube - 6AL7GT, Indicator
The 6AL7GT is an electron-ray indicator designed especially for use in AM-FM receivers. Through its use, precise tuning of either FM or AM signals is easily accomplished without the use of additional tubes or circuit components.
$6.90
Vacuum Tube - 6AN8A, Triode, Pentode
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.
$15.90
Vacuum Tube - 6AQ5A / 6HG5, Tetrode, Beam Power
Miniature beam-power pentode designed for use in the audio-frequency power output stage of television and radio receivers. It may also be used as a triode-connected vertical deflection amplifier in television receivers.
$9.90
Vacuum Tube - 6AQ6, Diode, Dual, Triode
Miniature double diode high mu triode designed for service as a combined first audio amplifier, detector, and AVC tube in radio receivers. However, the 6AQ6 employs a 150 mA heter.
$3.90
Vacuum Tube - 6AQ8, Electro-Harmonix
Electro-Harmonix 6AQ8 dual triode preamp tube. Made in Russia.
$46.60
$19.90
Vacuum Tube - 6AR5, Pentode, Power
Pentode power amplifier using the miniature construction. It is intended for service in AC and storage battery operated receivers where moderate power sensitivity and power output is desired.
$9.90
Vacuum Tube - 6AR6, Tetrode, Beam Power
Beam power amplifier designed specifically for applications requiring relatively high peak plate currents at negative grid potentials. It is constructed to withstand relatively high plate potentials.
$17.75
Vacuum Tube - 6AS7GA, Dual Triode, Low MU
High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Except for the use of a T-12 glass envelope, the 6AS7GA is identical to the 6AS7G.
$11.90
Vacuum Tube - 6AS7G / 6520, Dual Triode
High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Shouldered glass (ST-16) envelope.
$27.90
Vacuum Tube - 6AT6 / 6BK6, Dual Diode, Triode
Miniature, duplex-diode, high-mu triode designed for use as a combined detector, amplifier, and automatic-volume-control tube
$3.90
Vacuum Tube - 6AU6A / EF94, Pentode, Sharp Cut-Off
Miniature sharp cutoff pentode primarily designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. Its low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications
$7.90
Vacuum Tube - 6AV5GA, Tetrode, Beam Power
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
Vacuum Tube - 6AV6 / EBC91, Dual Diode, Triode
Miniature 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
Vacuum Tube - 6AV11, Triple Triode
Compactron containing three medium-mu triodes suitable for general-purpose amplifier, phase inverter, or oscillator applications.
$9.85
Vacuum Tube - 6AW8A, Triode, Pentode
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.
