Vacuum TubesThe 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 - 6BK7-A-B, Dual Triode, HF
Miniature twin triode designed primarily for use as a cascode amplifier at frequencies below approximately 300 megacycles.
Vacuum Tube - 6J6A / ECC91, Dual Triode, Medium MU
Twin triode in the 7 pin miniature construction. It can be operated in parallel or push-pull.
Vacuum Tube - 6688 / E180F, Philips, Pentode, RF, Gold Pin
Special quality pentode designed for use as wide band amplifier.
Vacuum Tube - 3Q4, Pentode, Power
The type 3Q4 is a miniature type power-amplifier pentode designed for use in the output stage of battery operated equipment.
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.
Vacuum Tube - 7581, Tung-Sol
Russian Tung-Sol 7581 tube. Beam power pentode with octal base. (May be substituted for 6L6GC). Made in Russia.
Vacuum Tube - 6AF4A / 6DZ4, Triode, UHF, Oscillator
Medium-mu triode in the 7-pin miniature construction. It is designed for local oscillator service in television receivers which operate in the UHF region, internal lead inductance is reduced by employing double connections to the plate and grid.
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 - 6BN6 / 6KS6, Discriminator, Gated Beam
Heater-cathode type beam tube of miniature construction designed primarily to form the combined operations of the limiter, discriminator, and audio-voltage amplifier in FM and intercarrier television receivers.
Vacuum Tube - 6HA5 / 6HM5, Triode, HI MU
Miniature triode designed particularly for service in VHF television tuners as a grounded-cathode RF amplifier.
Vacuum Tube - 26HU5, Beam Power Amplifier
Glass octal type used as horizontal-deflection amplifier in color television receivers.
Vacuum Tube - 0B3 / VR90, Voltage Regulator
The 0B3 is a two-element gas-filled, cold cathode voltage regulator. It is designed to provide regulated outputs of approximately 90 volts.
Vacuum Tube - 12AV5GA, Tetrode, Beam Power
Telefunken Brand. Miniature medium-mu twin triode intended for service in radio and television receivers or in audio amplifiers.
Vacuum Tube - 5755 / 420A, Dual Triode
The 420A electron tube is a double-triode having separate indirectly heated cathodes. The heater is center-tapped to permit operation from a 6.3 or 12.6 volt filament supply.
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.
Vacuum Tube - 12AD6 / 12AG6, Heptode
Miniature heptode primarily intended to perform the combined functions of mixer and oscillator in automobile radio receivers. Specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.
Vacuum Tube - 6M11, Triode, Dual - Pentode
New-Old-Stock (NOS) tube. Compactron twin-triode pentode.
Vacuum Tube - 6AJ5, Pentode, Sharp Cut-Off
Miniature sharp cutoff pentode designed for use where only low plate and screen voltages are available. The 6AJ5 is especially suitable for operation at high frequencies.
Vacuum Tube - AZ41, Rectifier, Full Wave
High vacuum full wave rectifying tube.
Vacuum Tube - 12DQ7, Pentode, Sharp Cut-Off
Miniature power pentode primarily designed for use as the video output amplifier in television receivers. Features of the tube include high transconductance, low interelectrode capacitances, and high power sensitivity.
Vacuum Tube - 37, Triode
General purpose triode designed for service as an oscillator, detector, or amplifier.
Vacuum Tube - 5672 / DL69, Pentode
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
