The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
Miniature sharp-cutoff pentode for use as a wide-band, high-frequency amplifier. It is also useful in video and audio amplifiers, oscillators, mixers, frequency multipliers, and cathode followers.
Subminiature pentode for use as an A.F. power amplifier in portable equipment.
Subminiature pentode for use as R.F, M.F., or A.F. amplifier, oscillator, self-oscillating mixer, A.M. detector etc.
Triode, Dual, Tung-Sol Brand
Sharp cutoff pentode intended for critical industrial applications where 10,000 hour life, extreme uniformity, rigid construction, and exceptional stability are paramount.
Triple grid general purpose detector amplifier.
Miniature pentagrid converter designed for use as a combined mixer and oscillator in superheterodyne circuits.
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.
Triple grid variable mu amplifier.
9-pin miniature triode with an indirectly heated cathode. It is intended primarily for grounded grid operation in the input stage of broad band amplifiers.
Out of Stock
The premium subminiature type 5902 is a beam power pentode designed for use as an audio amplifier. It is intended for operation under conditions of severe shock, vibration, high temperature, and high altitude.
Rugged beam amplifier tube designed for use in mobile transmitters or amplifiers which may be submitted to shock or vibration.
Miniature twin-triode primarily designed for service in computer applications. Each triode section features a high zero-bias plate current, a sharp-cutoff characteristic, and a separate cathode connection.
Filament-type high-vacuum full-wave rectifier designed for service in power supplies of moderate current requirements. The electrical characteristics of the 5AZ4 are equivalent to those of the 5Y3GT.
