New Old Stock (NOS)Our new-old-stock tubes were made by the major U.S. manufacturers, along with a small number of European manufacturers and are tested and guaranteed.
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.
The 4D21 / 4-125A is a four-electrode tube designed for use as a power amplifier and oscillator. The anode is capable of dissipating 125 watts, and cooling is accomplished by radiation.
Compact, quick heating thyratron designed for timing and control applications. It is xenon filled for quick starting and the ability to operate within very wide temperature limits.
Triode, Dual, Red Base
Triode, Globe, Long Pin
Beam pentode designed for use as a series regulator in high-voltage power supplies.
Isa negative control, xenon filled, four electrode thyratron designed for use in relay and grid-controlled rectifier applications. One type 6012 will carry 0.5 ampere in motor-control and in inverter service.
Duodecar type used as a horizontal deflection amplifier in color television receivers.
New-Old-Stock (NOS) tube.
Beam-deflection tube for use in balanced-modulator, balanced mixer, and frequency-converter applications in single and double sideband, suppressed-carrier communication equipment operating at frequencies up to 100 Mc.
Special quality pentode designed for use in telephone equipment.
Beam power tube for horizontal-deflection-amplifier service in black-and-white TV receivers.
Small, closely spaced, low-capacitance, high-vacuum diode designed for use through ultra-high frequencies. In measurement work, it is well suited to mounting in a probe and will maintain accuracy
The 5U4G is designed for service as a power rectifier in AC operated receivers which require high currents
Starting at $18.40
Twin medium-mu triode whose sections are electrically independent except for the common heater. It is designed especially for use in equipment where the operating voltages are obtained from a 12 cell storage battery
Filament type general purpose triode especially designed for use in low drain battery operated receivers.
416D - Triode, Planar
The 41 is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.
Starting at $7.55
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.
High vacuum full wave rectifying tube.
Special quality pentode designed for use as wide band amplifier.
The 7534 is designed to provide low hum, non-microphonic operation through the incorporation of a helical wound heater and rigid mounting of the internal components. The 7534 is otherwise similar to, and a replacement for, the 6AU6.
