# 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 - 6GH8A, Triode, Pentode
Miniature tube which contains a sharp-cutoff pentode and a medium-mu triode. Each section has a separate cathode and is electrically independent.
$6.90 Vacuum Tube - 12SQ7, Diode, Dual, Triode Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.$19.90
Vacuum Tube - 1R5 / DK91, Heptode
Miniature pentagrid-converter designed for use as a combined mixer and oscillator in superheterodyne circuits. Because of its small size and high operating efficiency, the 1R5 is especially adapted for compact, battery-operated equipment.
$5.90 Vacuum Tube - 6BN8, Dual Diode, Triode Miniature, high mu triode, double diode intended for application in color and monochrome television receivers. Separate cathode connections for each section and controlled heater warm-up time to insure dependable operation in series string receivers$8.95
Vacuum Tube - 6J7 / EF36, 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.
$6.90 Vacuum Tube - 6SQ7GT, Diode, Dual Triode Duplex-diode high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor$5.90
Vacuum Tube - 6E5, Indicator, Tubular 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.
$33.60 Vacuum Tube - 12SL7GT, Triode, Dual, HI-MU High-mu twin triode designed for use in resistance-coupled circuits as a voltage amplifier or phase inverter. Except for heater characteristics and ratings, the 12SL7GT is identical to the 6SL7GT.$6.90

Originally: $4.90 Vacuum Tube - 12SK7, Pentode, Remote Cut-Off The T-12SK7 is the same as the 6SK7 except for heater ratings.$6.90
Vacuum Tube - 12BH7A, Triode, Dual, Medium MU
Miniature, medium-mu twin triode designed primarily for use as a vertical-deflection amplifier in television receivers. The two sections may be employed in parallel, or as a combined vertical-deflection amplifier and vertical oscillator.
$29.90 Vacuum Tube - 12BV7 / 12BY7A, Pentode Miniature power pentode designed primarily for use as the video output amplifier in television receivers. Like the 12BY7, it features high transconductance, high power sensitivity, and low interelectrode capacitances.$13.90
Vacuum Tube - 12DQ6B / 12GW6, Beam Power Amplifier
Beam power pentode primarily designed for use as the horizontal-deflection amplifier in television receivers.
$11.90 Vacuum Tube - 12SA7, Heptode 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.$8.90
Vacuum Tube - 35L6GT, Beam Power Amplifier
Beam pentode primarily designed for use in the audio frequency power output stage of radio receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.
$8.90 Vacuum Tube - 0A2 / 150C2, Voltage Regulator, Diode, Glow-Discharge 0A2 or 150C2 - Voltage Regulator, Diode, miniature glow-discharge type.$6.90
Vacuum Tube - 6CB6A / 6CF6, Pentode, Sharp Cut-Off
Miniature pentode designed for use as a radio-frequency or intermediate-frequency amplifier in television receivers. Features of the tube include high transconductance and low interelectrode capacitances.
$3.90 Vacuum Tube - 6KD8 / 6U8A, Triode, Pentode Medium mu triode and sharp cutoff pentode in the 9 pin miniature construction. It is intended for use as a combined VHF oscillator and mixer in television receivers.$9.90
Vacuum Tube - 6SC7, Triode, Dual, HI-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.
$19.90 Vacuum Tube - 3V4 / DL94, Pentode, Power Miniature power amplifier pentode designed for use in the power output stage of compact, battery operated equipment. It is particularly useful in three-way portable receivers which employ 90-volta batteries.$8.90
