# 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.
Vacuum Tube - 5Y4GT, Rectifier, Full Wave
Full-wave vacuum rectifier. The 5Y4GT is the same as the 5Y4GA except for mechanical design.
$16.90 Out of Stock Vacuum Tube - 6DA5 / EM81, Indicator, Electron Ray Electron-ray tuning indicator$19.90
Vacuum Tube - 6DE7, Triode, Dissimilar Double
Miniature double triode in the 9 pin miniature construction. Section #1 is intended for use as a vertical deflection oscillator having medium mu and section 2 is intended for use as a vertical reflection amplifier with low mu.
$6.95 Vacuum Tube - 6X5GT / EZ35, Rectifier, Full Wave Cathode type rectifier designed particularly for use in automobile receivers.$12.90
Vacuum Tube - 6SC7GT, Dual Triode, High MU
High-mu twin triode designed primarily for use as an AF voltage amplifier. Featuring a special shielding arrangement to reduce hum, the tube is well suited for low-level audio amplifier service.
$44.90 Vacuum Tube - 1619, Beam Power Amplifier Transmitting beam power amplifier.$13.90
Vacuum Tube - 2A3, Triode
Filament type triode power amplifier. It is designed for service in the output stage of audio amplifiers where high output and low harmonic distortion is desired.
$179.90 Vacuum Tube - 930, Photocell, Sound New Old-Stock (N.O.S.) tube. The 930 is a gas phototube sensitive to red through infrared light.$24.95
Vacuum Tube - 43, Pentode
Glass type power amplifier pentode designed especially for use in the output stage of a-c/d-c receivers. The 43 is identical in electrical characteristics to the type 25A6 tube.
$7.90 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 - 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 - 1N5GT / 1P5GT, Pentode, Sharp Cut-Off, RF Filamentary type sharp cut-off pentode voltage amplifier. It is designed for service in low-drain battery-operated receivers as an RF, IF, or AF amplifier.$5.90
Vacuum Tube - 5881, Tung-Sol, Tetrode, Beam Power
The 5881 is the electrical equivalent to types 6L6 and 6L6GC except that the plate and screen dissipation ratings have been increased approximately 20 percent.
$149.90 Vacuum Tube - 5750 / 6BE6W, Heptode Miniature pentagrid converter designed for use as a combined mixer and oscillator in superheterodyne circuits.$4.90
Vacuum Tube - 6C10, Triple Triode
Contains three high-mu triodes with separate pin connections for all three cathodes, grids, and plates in a compact T-9 glass envelope with the novel 12 pin base.
$99.90 Out of Stock 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.$2.95

Originally: $5.90 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. Starting at$4.50
Vacuum Tube - 6L6, Tetrode, Beam Power, Metal
The 6L6 is designed with high power sensitivity and high efficiency for service in the output stages of AC receivers. They are capable of delivering an output at all power levels with a very low percentage of harmonic distortion.
$29.90 Vacuum Tube - 12J7GT, Pentode, Sharp Cut-Off Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.$3.90
Vacuum Tube - 12SG7, Pentode, Semi-Remote Cut-Off
Semi-remote cut off pentode voltage amplifier in the octal metal construction. It features high transconductance with low grid-plate capacitance and a dual cathode connection to minimize effects of common cathode circuit coupling.
$5.35 Vacuum Tube - 5763, Tetrode, Beam Power Heater-cathode type transmitting beam power amplifier in the 9 pin miniature construction. It is intended for use in compact, low-power mobile transmitters and in the low-power stages of larger fixed station transmitters.$6.45
