# 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 - 32, Tetrode
Sharp cut-off tetrode designed for use as a radio-frequency or intermediate-frequency amplifier or as a detector tube in battery operated receivers.

Originally: $4.90 Vacuum Tube - 6C5G, Triode, Detector Amp General purpose triode designed for service as an oscillator, detector, or amplifier. It is similar in characteristics to the 6C6, 6J7, and 57 with triode connection.$39.90
Vacuum Tube - 6DQ5, Pentode, Beam Power
Beam power tube for use as a horizontal-deflection amplifier tube in color and black-and-white television receivers.
$14.90 Vacuum Tube - 6DZ7, Dual Pentode, Power Twin power pentode designed for use in the output stage of high-fidelity audio amplifiers. The incorporation of two pentode sections in one envelope makes it especially suitable for compact stereo systems.$33.90
Vacuum Tube - 6E5, Indicator, ST Shape Glass
High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.

Vacuum Tube - 6F6G, Pentode, Power Amplifier
Pentode amplifier designed for application in power output stages of receivers
$59.90 Vacuum Tube - 6GM8 / ECC86, Dual Triode Frame-grid twin triode designed for low supply voltage applications. It is especially suitable for instrumentation/industrial use as a direct-coupled wide band amplifier and for automobile radio as an RF amplifier and self-oscillating mixer.$24.90
Vacuum Tube - 6J7GT, 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.
$11.90 Vacuum Tube - 6JM6-A, Beam Power Amplifier Duodecar type used as a horizontal-amplifier tube in color and black-and-white television receivers.$4.95
Vacuum Tube - 6KG6A / EL509, Beam Power Amplifier
Magnoval type used as a horizontal-deflection amplifier in color television receivers.
$44.50 Out of Stock Vacuum Tube - 6N6G, Triode, Amplifier Consists of two dynamically coupled triodes and is designed for service in the power output stage of AC and storage battery operated receivers. All necessary biases are supplied internally$39.90
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.
