Vacuum Tubes
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.
Rated for more power than the standard 7581 (35W plate dissipation vs 30W plate dissipation).
Starting at $46.60
Beam power tube of the 9-pin miniature type designed for use as the output amplifier in automobile radio receivers operating from a 12-volt storage battery. The 12AB5 can provide high power output.
$5.90
Medium-mu twin triode intended for service in radio and television receivers or in audio amplifiers. The tube is suitable for use in a variety of stages, such as general-purpose amplifier, phase inverter, oscillator, or multivibrator.
$22.90
Miniature medium-mu twin triode designed primarily for use in low-level stages of high-gain audio-frequency amplifiers. The tube is specially designed to exhibit low noise and low microphonic output.
$49.90
Low-voltage, low-current drain, battery type power pentode. It is designed for service with 90 volts of "B" battery and a single dry cell "A" battery.
$11.90
Triple grid variable MU amplifier. It is suitable for use with AVC in RF and IF amplifiers as it minimizes cross modulation
$6.90
Diode and a remote cutoff pentode with a common cathode of the 9 pin miniature type especially designed for use as combined IF amplifier and AM detector tubes in AM and AM/FM broadcast receivers.
$4.90
Pentode amplifier designed for application in power output stages of receivers
$27.90
Compactron device containing two high-mu triodes and one medium-mu triode. Features of the tube include separate pin connections for all three cathodes, grids, and plates; an internal shield between sections 1 and 3.
$43.90
Combines two diodes and a high-mu triode using a common cathode. It is designed for service as a diode detector, AVC rectifier, and as a high gain resistance coupled amplifier in AC, storage battery, and AC - DC operated receivers.
