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.
General purpose medium-mu double triode using the 9-pin button all-glass construction. The tube is characterized by high perveance and high emission capabilities.
Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.
Triode, Dual, Red Base
Cathode type rectifier designed particularly for use in automobile receivers.
Xenon filled four electrode thyratron with negative control characteristic. This tube is designed for relay applications for grid-controlled rectifier service.
Miniature sharp cutoff pentode primarily designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. Its low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications
Beam pentode for power amplifier, oscillator, and modulator applications.
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
Starting at $17.60
General purpose triode designed for service as an oscillator, detector, or amplifier. Except for heater voltage and current its characteristics are identical with those of the 56.
The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.
Compactron containing two medium-mu triodes and one high-mu triode.
The 6K6GT 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.
Half-wave rectifier in the 7 pin miniature construction. Features of the tube are a 100mA. heater with 20 second warm-up time.
Designed primarily for service as a power rectifier in ac-dc receivers. Two separate rectifier sections permit using the tube as a voltage doubler, full wave rectifier, or half wave rectifier.
