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.
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
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
Low-voltage, low-current drain, battery type triode. It is designed for service as an oscillator, detector, or amplifier in receivers using 90 volts "B" battery and a single dry cell "A" battery.
$7.90
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
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.
$5.90
Out of Stock
General purpose medium-mu triode. It is useful for service as an oscillator or audio-frequency amplifier.
$5.90
Filament type power-amplifier pentode tube designed for use in the output stage of battery operated equipment.
$4.90
Medium-mu twin triode 9-pin miniature type, intended for applications where dependable performance under shock and vibration is paramount. The 5814A is a "premium" version of the 12AU7.
$16.90
The 5Y4G is designed for use as a power rectifier in AC operated receivers.
$24.90
Compactron containing three high-mu triodes. It is designed for use primarily as a color-difference amplifier in color television receivers.
$7.90
High-slope R.F. pentode particularly suitable for use in F.M. receivers.
$24.95
High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.
$33.60
Sharp cut-off amplifier pentode designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. The 6SH7 is not recommended for use as a high-gain audio amplifier because undesirable hum may be encountered.
$4.90
Rated for more power than the standard 7581 (35W plate dissipation vs 30W plate dissipation).
Starting at $46.60
Tung Sol EF806 SG pentode preamp tube with gold pins. Made in Russia. Super premium EF86/6267 replacement based on the Telefunken EF806S. Super low noise and microphonics. Gold pins.
$51.25
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.
$23.95
Miniature low-mu triode designed primarily for service as a vertical-deflection amplifier in television receivers. The tube features high plate current at relatively low plate voltages
$5.90
Genalex Gold Lion U77 / GZ34 full-wave rectifier tube. Made in Russia.
$62.90
The 5R4GY is designed for rectifier use in equipment requiring a high peak inverse voltage rating. Satisfactory operation of this tube type under conditions falling within area 1 on curve no 1 may be obtained without filament preheating.
$24.90
Full-wave rectifier of the heater-cathode type intended for use in AC operated and automobile receivers. Because of its heater-cathode construction it has the same heating time as that of other heater-cathode types in the receiver.
