Vacuum Tube - 6DA4-A / 6DM4, Diode, Damper
Half-wave vacuum rectifier employing a T-9 envelope. It is designed specifically for use as a damper diode in horizontal-deflection circuits of black-and-white television receivers
Vacuum Tube - 7B8, Heptode
Pentagrid converter designed to perform the combined functions of the oscillator and mixer in superheterodyne receivers
Vacuum Tube - 6H6, GE JAN, Dual Diode
GE JAN, Dual Diode
Vacuum Tube - 6BY7 / EF85, Pentode
R.F. pentode with variable transconductance for use as wide-band amplifier.
Vacuum Tube - 50Y6GT, Rectifier, DoubleR

The 6K7G is an indirectly heated pentode of the vari-mu (remote cut-off) type for use in the RF or IF stages of radio equipment.
Vacuum Tube - 6CT7 / EAF42, Pentode
Single diode, remote cut-off R.F. pentode.
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 - 35B5, Tetrode, Beam Power
Miniature beam power amplifier especially designed for use in the power output stage of a-c/d-c receivers. Its small size and high efficiency make the tube especially useful where space limitation prevent the use of larger types.
Vacuum Tube - 6BQ7A / 6BZ7, Dual Triode
Miniature, medium-mu twin triode primarily designed for use as a cascode, radio-frequency amplifier in very high frequency television tuners. In this application, its performance is characterized by high gain and low noise figure.
Vacuum Tube - 1S5 / DAF91, Diode, Sharp Cut-Off Pentode
Miniature tube containing a diode and a sharp-cutoff pentode. It is designed for use as a combined detector and audio-frequency voltage amplifier in compact battery-powered equipment.
Vacuum Tube - 6AH6, Pentode, Sharp Cut-Off
Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.
Vacuum Tube - 12SJ7, Pentode, Sharp Cut-Off
A single-ended RF pentode having sharp cut-off characteristics. It is designed for use as a general purpose amplifier, biased detector, radio frequency oscillator or as a mixer tube in properly designed circuits.
Vacuum Tube - 6AG5 / EF96, Pentode
Miniature type RF pentode having a sharp cut-off characteristic and a high value of transconductance. In compact, light-weight equipment it is useful as an RF amplifier up to about 400 megacycles.
Vacuum Tube - 6AT6 / 6BK6, Dual Diode, Triode
Miniature, duplex-diode, high-mu triode designed for use as a combined detector, amplifier, and automatic-volume-control tube
Vacuum Tube - 6CA5 / 6EH5, Tetrode, Beam Power
Miniature beam power pentode designed for service as an audio output amplifier. It features high power sensitivity at relatively low plate and screen voltages.
Vacuum Tube - 6DG6GT / 6W6GT, Beam Power Amplifier
Beam power pentode intended for service as an audio power amplifier.
Vacuum Tube - 6DT8, Dual Triode
Miniature, high-mu, twin triode designed for use as a radio frequency amplifier or as a combined oscillator and mixer in FM receivers.
Vacuum Tube - 7Y4, Rectifier, Full Wave
Heater type vacuum twin diode using the lock-in construction. It is intended for use as a full-wave rectifier in either AC or storage operated equipment where economy of heater power is desired.
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 - 0Z4-A, Rectifier, Full Wave, Gas
The 0Z4A is a gas-filled, double diode employing an ionic-heated cathode. Its principal application is as a full-wave power rectifier in equipment with vibrator type power supplies.
