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.
Vacuum Tube - 1H5GT-G, Diode, Triode, High MU
Tube containing a single diode and a high-mu triode in one bulb. It is designed for service as a diode detector, AVC rectifier, and as a resistance-coupled amplifier.
Vacuum Tube - 50B5, Beam Power Amplifier
Miniature beam-power amplifier designed primarily for use in the output stage of compact a-c/d-c receivers. The 50B5 features high power sensitivity and is capable of providing a relatively high power output
Vacuum Tube - 6CB6A / 6CF6, Pentode, Sharp Cut-Off
Miniature pentode designed for use as a radio-frequency or intermediate-frequency amplifier in television receivers. Features of the tube include high transconductance and low interelectrode capacitances.
Vacuum Tube - 6SA7, Heptode
Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.
Vacuum Tube - 7A8, Octode Converter
The 7A8 is an octode converter designed to perform the combined functions of the oscillator and mixer in superheterodyne receivers.
Vacuum Tube - 6AQ6, Diode, Dual, Triode
Miniature double diode high mu triode designed for service as a combined first audio amplifier, detector, and AVC tube in radio receivers. However, the 6AQ6 employs a 150 mA heter.
Vacuum Tube - 12JT6A, Beam Power Amplifier
The 12JT6A is the same as the 6JT6A except for heater characteristics and ratings.
Vacuum Tube - 6211-A, Dual Triode, Medium MU
Miniature, medium-mu twin triode for service in electronic computers. The electrical characteristics are essentially equivalent to those of the 5844.
Vacuum Tube - 6GV8 / ECL85, Triode, Pentode, Power
Combined triode and beam pentode especially intended for use in vertical output stage, particularly 110 degree picture tubes. Special attention has been paid to properties important for this application, such as microphonism and linearity.
Vacuum Tube - 32, Tetrode
Sharp cut-off tetrode designed for use as a radio-frequency or intermediate-frequency amplifier or as a detector tube in battery operated receivers.
Vacuum Tube - 6SH7GT, Pentode, Sharp Cut-Off, RF
Triple grid sharp cut-off amplifier. It is designed for service in high gain RF and IF amplifier applications and for limited service in FM receivers. The double cathode connection is useful in reducing cathode circuit coupling.
Starting at $4.50
Vacuum Tube - 7B6, Dual Diode, Triode
Combined high-mu triode and double diode using the 8 pin lock-in construction. It is designed for use as a diode detector, AVC rectifier, and an impedance or resistance coupled amplifier.
Vacuum Tube - 5651A, Voltage Reference
Voltage-reference tube, 7-pin miniature, glow-discharge type. Especially useful as a voltage reference tube in DC power supplies.
Vacuum Tube - 5670 / 2C51W, Triode, Dual
Miniature medium-mu twin triode each section of which as a separate cathode connection. The tube is suited for use in a wide variety of general-purpose amplifier and mixer circuits as well as numerous multi-vibrator and oscillator applications.
Vacuum Tube - 5749 / 6BA6W, Pentode, Remote Cut-Off
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.
Vacuum Tube - 6AK6, Pentode
Heater-cathode type of tube intended for use in compact, light-weight equipment. Because of its small size, the 6AK6 can be used singly or in push-pull to effect a more compact design of power-line receivers.
Vacuum Tube - 6AL5 / 6EB5, Dual Diode
The 6AL5 combines two independent diode units in the 7 pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.
Vacuum Tube - 6AW8A, Triode, Pentode
Miniature tube containing a high-mu triode and a sharp-cutoff pentode. The triode section is intended for service as a sync separator and the pentode section as a video amplifier.
Vacuum Tube - 6H6, Diode, Twin
Twin-diode with individual cathodes brought out to separate base pins. The 6H6 is designed for service as a diode detector, automatic volume control rectifier, or as a low current power rectifier
Vacuum Tube - 6SF5, Triode
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
Vacuum Tube - 6SH7, Pentode, Sharp Cut-Off, RF
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.
