Vacuum Tube - 5726 / 6AL5W, Dual Diode
Twin diode miniature type intended for applications where dependable performance under shock and vibration is paramount. The 5726 is a "premium" version of the 6AL5W
Vacuum Tube - 5751, Sovtek
Sovtek 5751 dual triode.
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 - 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 - 5AR4, Chinese
Chinese 5AR4 Vacuum Tube
Vacuum Tube - 6688 / E180F, Philips, Pentode, RF, Gold Pin
Special quality pentode designed for use as wide band amplifier.
Vacuum Tube - 6689 / E83F, Pentode, Wide Band Amplifier
Special quality pentode designed for use in telephone equipment.
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 - 6AS5, Tetrode, Beam Power
Miniature beam pentode designed primarily for use in the audio-frequency power output stage of automobile receivers. The tube is capable of delivering a relatively high power output at low plate and screen voltages.
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 - 6BJ7, Triple Diode
Miniature, triple diode primarily intended for use as a d-c restorer in each of the three signal channels of color television receivers. For flexibility in circuit design, each diode incorporates a separate cathode
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 - 6BN4A, Triode, HF
Miniature medium-mu triode designed for as a radio-frequency amplifier in a VHF television tuner.
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 - 6BS8, Dual Triode
Miniature, medium-mu twin triode designed for use as a VHF cascode amplifier. In this application, section two (pins 1, 2, and 3) is intended for the input section.
