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 - 6B4G, Triode, Power Amplifier
Glass triode power amplifier tube designed particularly for service in the power output stages of storage battery operated or a-c receivers
Vacuum Tube - 6BA7, Heptode
Cathode type high gain pentagrid converter in the small 9 pin button construction. It is designed for service as a combined local oscillator and mixer at high frequencies, especially in the FM broadcast band.
Vacuum Tube - 6BY5G, Dual Rectifier
Isa full-wave high-vacuum rectifier designed for damper service in television deflection circuits. It can also be used in conventional rectifier applications.
Vacuum Tube - 6BY6, Heptode
Miniature dual-control heptode designed primarily for use as a combined sync separator and sync clipper in television receivers. Each of the two independent control grids exhibits a sharp cutoff characteristic.

Vacuum Tube - 6F7, Pentode
Combines a triode and a remote cut-off pentode, utilizing a common cathode, in a single bulb.
Vacuum Tube - 6K5GT, Triode, HI MU
Cathode type high mu triode designed for use in high gain resistance coupled circuits. A lower amplification factor enables the use of a large signal input both under 250 volt and 100 volt operating conditions.
Vacuum Tube - 6K6G, Pentode
The 6K6G 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.

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.
Vacuum Tube - 6P5GT, Triode, Medium MU
General purpose triode designed for service as an oscillator, detector, or amplifier
Vacuum Tube - 7027-A, Tetrode, Beam Power
Beam power tube for high-fidelity audio-amplifier applications.
Vacuum Tube - 7199, Triode, Pentode
Triode-pentode designed primarily for high fidelity audio applications. The pentode section is particularly suited to preamplifier service while the triode section is intended for use as a phase inverter.
Vacuum Tube - 7355, Beam Power Amplifier
Beam-power pentode primarily designed for use in the power output stage of high-fidelity audio-frequency amplifier systems.

Vacuum Tube - 813, Beam Power Amplifier
General-purpose transmitting beam power tube of the thoriated-tungsten filament type designed for use as an rf power amplifier and oscillator as well as an af power amplifier and modulator.
Vacuum Tube - 930, Photocell, Sound
New Old-Stock (N.O.S.) tube. The 930 is a gas phototube sensitive to red through infrared light.
Vacuum Tube - EL84, Groove Tubes, Matched Pair
Package of 2
Groove Tube's Gold Series EL84. The warmest Groove Tube in this family. It remains very buttery, with relatively high power output and very even response. A great replacement for many modern stock amps, overcoming a variety of design issues and limitations in inexpensive tube amps.

Vacuum Tube - KT90, Electro-Harmonix
Electro-Harmonix KT90 power tube. Made in Russia.
Absolutely the best KT90 ever developed. Wafer base height of 0.34”.
Starting at $80.20
Vacuum Tube - 12B7 / 14A7, Pentode, Remote Cut-Off
Pentode type amplifier tube with remote cutoff characteristics designed for use as a high frequency amplifier in radio receivers.
Out of Stock
Vacuum Tube - 12BL6, Pentode
Miniature remote-cutoff pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers.
Vacuum Tube - 12SC7, Dual Triode, HI-MU
The type 12SC7 is a twin-triode amplifier designed for use as an audio amplifier or phase inverter. Special shielding arrangement in the base permits operation at a low hum level.
Vacuum Tube - 14F8, Dual Triode
High-transconductance twin triode designed for use in VHF circuits as a cathode follower, grounded-grid amplifier, or frequency converter. Except for heater voltage and current ratings, it is identical to the 7F8.
Vacuum Tube - 20LF6, Pentode, Beam
Beam power pentode designed for use in horizontal deflection circuits of color television receivers.
