Vacuum Tube - 25CD6G, Beam Pentode
New Old Stock (N.O.S.) tube. 25CD6GB is identical to the 6CD6GA except with different heater ratings. Beam power tube, octal base.
Vacuum Tube - 25L6, Beam Power Amplifier, Metal
Power-amplifier tube of the all-metal type for use in the output stage of transformerless (ac/dc) radio receivers, especially those designed to have ample reserve of power-delivering bilities.
Vacuum Tube - 6384, Beam Power Amplifier
High-perveance beam power amplifier designed as a direct retrofit for the 6AR6 or 6098 in aircraft, military, and industrial applications
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 - 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 - 6GT5-A, Beam Power Amplifier
Beam power tube for horizontal deflection amplifier service in black-and-white TV receivers.
Vacuum Tube - 12AJ6, Duplex Diode, Triode
Miniature double didoe, high-mu triode intended for use as a second detector audio amplifier. It is designed for operation where the heater and plate voltages are supplied directly from a 12-volt automotive storage battery.
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 - 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.
Vacuum Tube - 11MS8, Triode, Pentode
Miniature type used in combined vertical-deflection-oscillator and vertical-deflection-amplifier applications in black and white television receivers. Requires miniature 9-contact socket.
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 - 407A, Dual Triode, Medium MU
9-pin miniature double triode with separate indirectly heated cathodes. It is designed for use in amplifier, mixer, oscillator, multivibrator and clamp circuits. The useful frequency range extends through the VHF range.
Vacuum Tube - 50BM8 / UCL82, Triode, Pentode, Power
Miniature type triode-pentode designed for use as an AF amplifier by triode section and AF power amplifier by pentode section in radio receivers.
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 - 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.
