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 - 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 - 6D6, Pentode, Remote Cut-Off
Triple grid variable MU amplifier. It is suitable for use with AVC in RF and IF amplifiers as it minimizes cross modulation
$6.90
Vacuum Tube - 6EQ7, Diode, Pentode
Diode and a remote cutoff pentode with a common cathode of the 9 pin miniature type especially designed for use as combined IF amplifier and AM detector tubes in AM and AM/FM broadcast receivers.
$4.90

$3.90
Vacuum Tube - 41, Pentode, ST Glass
The 41 is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.
$19.90
Vacuum Tube - 42, Pentode, Power Amplifier, ST Glass
42 is a pentode amplifier designed for application in power output stages of receivers
Starting at $15.80
Vacuum Tube - 6C6, Pentode, Sharp Cut-Off
Triple grid general purpose detector amplifier. With the exception of capacitance, its electrical characteristics are identical with those of the 6J7G and 6J7GT.
$8.90
Vacuum Tube - 6GV8 / ECL85 /ECL805, Triode, Pentode, Power
Combined triode and beam pentode especially intended for use in vertical output stage, particularly 110 degree picture tubes. Special attention has been paid to properties important for this application, such as microphonism and linearity.
$4.45
Vacuum Tube - 12SK7GT, Pentode, Remote Cut-Off, RF
Single ended cathode type super control pentode primarily designed for amplifier service in radio or intermediate frequency circuits. In properly designed superheterodyne circuits it may also be used as a mixer tube.
$6.90
Vacuum Tube - 6AG7 / 6AK7, Pentode, Power
Metal, power-amplifier pentode primarily designed for use in the output stage of video amplifiers. The tube is capable of operating at high plate current levels and exhibits high transconductance and high power sensitivity.
$7.90
Vacuum Tube - 6BZ6 / 6JH6, Pentode, Semi-Remote Cut-Off
Miniature semi-remote-cutoff pentode designed primarily for use as an intermediate frequency amplifier in television receivers.
$5.90
Vacuum Tube - 6DC6, Pentode, Semi-Remote Cut-Off
Semi-remote cutoff pentode. It is designed for service in the IF stages of color and monochrome television receivers and may be used in the tuners of such sets as an AF amplifier.
$7.90
Vacuum Tube - 6SH7GT, Pentode, Sharp Cut-Off, RF
Triple grid sharp cut-off amplifier. It is designed for service in high gain RF and IF amplifier applications and for limited service in FM receivers. The double cathode connection is useful in reducing cathode circuit coupling.
