# 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 - 12B4A, Triode, Low MU
Miniature low-mu triode designed primarily for service as a vertical-deflection amplifier in television receivers. The tube features high plate current at relatively low plate voltages
$5.90 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
Vacuum Tube - 6AX5GT, Rectifier, Full Wave
Full-wave rectifier of the heater-cathode type intended for use in AC operated and automobile receivers. Because of its heater-cathode construction it has the same heating time as that of other heater-cathode types in the receiver.

Vacuum Tube - 14N7, Dual Triode
Combines two low-mu triodes in the lock-in construction. It is designed for use either as a phase inverter or as a voltage amplifier.
$5.90 Vacuum Tube - 0B2, Voltage Regulator, Diode, Glow-Discharge The 0B2 is a two-electrode, inert-gas-filled cold cathode miniature tube intended for use as a voltage regulator.$5.90
Vacuum Tube - 7A7, Pentode, Remote Cut-Off
Pentode voltage amplifier using the lock-in construction. It is designed for RF or IF service in AC/DC receivers.
$5.90 Vacuum Tube - 6J11, Dual Pentode Compactron device containing two sharp cutoff pentodes, designed primarily for intermediate-frequency amplifier service in television receivers.$5.90
Vacuum Tube - 12AV6, Diode, Dual Triode
Combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier.
$5.90 Vacuum Tube - 12SA7GT, Pentagrid Converter Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.$5.90
Vacuum Tube - 12J5GT, Triode, Medium-MU
General purpose medium-mu triode. It is useful for service as an oscillator or audio-frequency amplifier.
$5.90 Vacuum Tube - 26A6, Pentode R-F amplifier pentode, miniature remote-cutoff type, for use with 12-cell storage battery supply.$5.90
Vacuum Tube - 6FD7, Dual Triode, Dissimilar
Dissimilar section double triode intended to serve the combined functions of the vertical deflection oscillator and amplifier. It features the T-9 bulb with integral wafer base which fits the standard 9 pin miniature socket.
$5.90 Vacuum Tube - 6Y6G, Tetrode, Beam Power Beam power amplifier having high power sensitivity and high power output at comparatively low DC supply voltages.$5.90
Vacuum Tube - 50EH5, Pentode, Power Amplifier
Miniature power pentode primarily designed for use in the audio-frequency power output stage of radio receivers and phonographs. The tube features high power sensitivity at low plate and screen voltages.
$5.90 Vacuum Tube - 3A4, Pentode, Power Amplifier The 3A4 is designed for use in compact, lightweight, portable equipment. The relatively large filament employed in the 3A4 enables it to supply the high peak currents required in RF power applications.$5.90
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 - 12AB5, Tetrode, Beam Power Beam power tube of the 9-pin miniature type designed for use as the output amplifier in automobile radio receivers operating from a 12-volt storage battery. The 12AB5 can provide high power output.$5.90
Vacuum Tube - 6L7, Heptode
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 Vacuum Tube - 77, Pentode, Sharp Cut-Off Triple grid general purpose detector amplifier.$5.90
