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.

T-6FM7 Vacuum Tube - 6FM7, Dual Triode, Dissimilar
Compactron dissimilar double triode designed for used as a combined vertical-deflection oscillator and amplifier in television receivers.
$4.90
T-6L7G Vacuum Tube - 6L7G, Pentagrid Mixer
Mixer tube designed for service with a separate oscillator as the first detector in superheterodyne receivers. The control grid is of the remote cut-off type which allows the use of AVC and minimizes cross-modulation.
$5.90
T-6SN7GT-B Vacuum Tube - 6SN7GT(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. It is also especially useful as a blocking oscillator, multivibrator, or vertical deflection amplifier in television receivers.
$22.95
T-6SS7 Vacuum Tube - 6SS7, Pentode, Remote Cut-Off
The 6SS7 is an RF pentode which as remote plate current cutoff. It is suitable for operating with AVC in Rf and IF amplifiers. The use of this tube will reduce cross modulation effects.
$6.90
T-7025 Vacuum Tube - 7025, Triode, Dual, High MU
Miniature, high-mu, twin triode primarily designed for use in low-level stages of high-gain audio-frequency amplifiers. Use of the 7025 in this application is advantageous because of its low hum output.
$59.95
