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.
9-pin miniature double triode with separate indirectly heated cathodes. It is designed for use in amplifier, mixer, oscillator, multivibrator and clamp circuits. The useful frequency range extends through the VHF range.

Originally: $9.95
Combines two independent diodes in the lock-in construction permitting the tube to be used as a power rectifier in either half-wave, full-wave, or voltage doubler applications.
$4.90
Heather cathode type tube consisting of two diodes and a triode in a single bulb. It is designed for use as a combined detector, amplifier, and automatic volume control.
$7.90
Full-wave vacuum rectifier. The 5Y4GT is the same as the 5Y4GA except for mechanical design.
$16.90
Miniature high-mu twin triode especially suited for use in resistance-coupled voltage amplifier, phase inverters, multivibrators, and other applications in which high voltage gain is desired.
$49.90
Triode using the miniature construction. Its low capacitance and high ratio of plate current to transconductance allow use as a high frequency oscillator and mixer at frequencies below ~300 mc or as grounded grid radio frequency amplifier.
$24.90
Beam power amplifier designed specifically for applications requiring relatively high peak plate currents at negative grid potentials. It is constructed to withstand relatively high plate potentials.
$17.75
Consists of two dynamically coupled triodes and is designed for service in the power output stage of AC and storage battery operated receivers. All necessary biases are supplied internally
$24.70
Cathode type high gain pentagrid converter in the small 9 pin button construction. It is designed for service as a combined local oscillator and mixer at high frequencies, especially in the FM broadcast band.
$9.90
General purpose triode designed for service as an oscillator, detector, or amplifier. It is similar in characteristics to the 6C6, 6J7, and 57 with triode connection.
$39.90
Dissimilar double triode utilizing the 9T9 bulb and pin configuration. The tube is designed to serve as a combined vertical deflection oscillator and amplifier.
$7.90
Converter tube designed for stable operation over an extended frequency range. It consists of a heptode mixer and a triode oscillator, having a common cathode. The injector grid of the heptode is internally connected to the triode grid.
$18.90
Compactron beam power pentode designed for use as a horizontal deflection amplifier in color television sets.
$61.00
Cathode type high mu triode designed for use in high gain resistance coupled circuits. A lower amplification factor enables the use of a large signal input both under 250 volt and 100 volt operating conditions.
$5.90
Beam power amplifier tetrode designed for use in the output stage of radio receivers or other equipment requiring high power output, power sensitivity and efficiency.
$29.90
Heater-cathode type high-mu triode designed for service as a high gain audio-frequency amplifier and is especially useful in resistance-coupled amplifier circuits in a-c or battery operated equipment
$6.95
Out of Stock
Rugged high mu twin triode designed for service as a resistance coupled amplifier or phase inverter in applications requiring resistance to shock and vibrations.
$40.95
Beam-power pentode primarily designed for use in audio-frequency power-amplifier applications. The 7581A is unilaterally interchangeable with the 7581 and the 6L6GC.
$99.90
Miniature, medium-mu triode intended primarily for use as a vertical-deflection amplifier in television receivers. The tube features high plate current at low plate voltages
$4.90
Gas-filled ballast tube designed to maintain a relatively constant current over a specified operating range.
$89.90
Rugged full-wave filamentary type rectifier designed for use in applications requiring resistance to shock or vibration.
$34.90
The 5X4 is designed for service as a power rectifier in AC operated receivers which require high currents
$12.90
High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Except for the use of a T-12 glass envelope, the 6AS7GA is identical to the 6AS7G.
