Vacuum Tube - 2A3, Triode, Power Amplifier, Single Plate
Triode, Power Amplifier, Single Plate
Starting at $263.85 Out of Stock Vacuum Tube - 2A5, Pentode, Power Amplifier Type 2A5 is a pentode amplifier designed for application in power output stages of receivers. With the exception of heater ratings, their electrical characteristics are identical. Starting at$11.65
Partially Out of Stock
Vacuum Tube - 2A6, Dual Diode, Triode
Heater-cathode type duplex-diode high-mu triode designed for use as a combined detector, audio-frequency amplifier and automatic-volume-control tube. Except for heater rating the 2A6 and 75 are identical.
$7.90 Vacuum Tube - 2A7, Pentagrid Converter Are pentagrid converters designed for service as oscillators and mixers in ac operated and ac-dc operated receivers. With the exception of heater ratings, they have identical rating and electrical characteristics.$9.90
Vacuum Tube - 2D21 / PL21, Thyratron
Miniature, four-electrode, inert-gas-filled thyratron with negative control characteristics of the tube include a high control ratio essentially independent of temperature over a wide range low grid-anode capacitance and very low grid current.
$6.90 Vacuum Tube - 2E26, Pentode, Beam V-H-F beam power amplifier.$6.90
Vacuum Tube - 30, Triode
General purpose filament type triode designed for service in battery operated receivers. With the exception of capacitances, its ratings and characteristics are identical with those of the 1H4G.
$19.90 Vacuum Tube - 30KD6, Beam Power Amplifier Duodecar type used as horizontal-deflection amplifier in television receivers.$39.90
Vacuum Tube - 31, Triode
Power amplifier.
$16.90 Out of Stock Vacuum Tube - 35A5, Tetrode, Beam Power Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. It has high power sensitivity and high efficiency at relatively low plate and screen voltages.$6.90
Vacuum Tube - 35Y4, Rectifier, Half Wave
Half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. The heater is tapped to permit operation of a panel lamp.
$8.90 Vacuum Tube - 35Z3, Rectifier, Half Wave Half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. Electrically the 35Z3 is equivalent to the 35Z5GT except that the heater of the 35Z3 is not tapped for operation of a panel lamp.$5.90
Vacuum Tube - 36KD6 / 40KD6, Beam Power Amplifier
Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. It is characterized by having a very low knee with a very high peak current of over an ampere.
$29.90 Out of Stock Vacuum Tube - 37, Triode General purpose triode designed for service as an oscillator, detector, or amplifier.$14.90
Vacuum Tube - 3A4, Pentode, Power Amplifier
The 3A4 is designed for use in compact, lightweight, portable equipment. The relatively large filament employed in the 3A4 enables it to supply the high peak currents required in RF power applications.
$5.90 Vacuum Tube - 3A5 / DCC90, Dual Triode The 3A5 is intended for use in high frequency applications. The relatively large filament employed in the 3A5 enables it to supply the high peak currents required in RF power applications.$5.90
