Miniature twin triode designed primarily for use as a cascode amplifier at frequencies below approximately 300 megacycles.
Vacuum Tube - 6JT6A, Beam Power Amplifier
Beam power tube for horizontal-deflection-amplifier service in black-and-white TV receivers.
Vacuum Tube - AZ41, Rectifier, Full Wave
High vacuum full wave rectifying tube.
Vacuum Tube - 6BY7 / EF85, Pentode
R.F. pentode with variable transconductance 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 - 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 - 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 - 6HA5 / 6HM5, Triode, HI MU
Miniature triode designed particularly for service in VHF television tuners as a grounded-cathode RF amplifier.
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.
Vacuum Tube - 6CN7, Dual Diode, Triode
Duplex-diode high-mu triode in which separate cathodes are provided for the diode and triode sections. The tube is primarily intended for service as a combined horizontal phase detector and reactance tube in television receivers.
Vacuum Tube - 8950, Pentode, Power Amplifier
Compactron beam power pentode primarily designed for RF power output applications. Features of the 8950 are dual cathode and grid connections for lower lead inductance, and a 13 volt heater.
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 - 6CT7 / EAF42, Pentode
Single diode, remote cut-off R.F. pentode.
Vacuum Tube - 6AU4GTA, Diode, Damper
Single heater-cathode type diode intended for service as the damping diode in the horizontal-deflection circuit of television receivers. High output current capabilities make the tube particularly well suited for autotransformer deflection systems
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.
