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.

Originally: $5.90
Miniature tube containing a diode and a sharp-cutoff pentode. It is designed for use as a combined detector and audio-frequency voltage amplifier in compact battery-powered equipment.
$3.55
Miniature beam power amplifier especially designed for use in the power output stage of a-c/d-c receivers. Its small size and high efficiency make the tube especially useful where space limitation prevent the use of larger types.
$3.55
Miniature, medium-mu twin triode primarily designed for use as a cascode, radio-frequency amplifier in very high frequency television tuners. In this application, its performance is characterized by high gain and low noise figure.
$3.55
Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.
$3.55
Miniature double didoe, high-mu triode intended for use as a second detector audio amplifier. It is designed for operation where the heater and plate voltages are supplied directly from a 12-volt automotive storage battery.
$3.90
The 7A8 is an octode converter designed to perform the combined functions of the oscillator and mixer in superheterodyne receivers.
$3.90
Miniature beam power pentode designed for service as an audio output amplifier. It features high power sensitivity at relatively low plate and screen voltages.
$3.90
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.
$3.90
Vacuum Tube - 0Z4-A, Rectifier, Full Wave, Gas
The 0Z4A is a gas-filled, double diode employing an ionic-heated cathode. Its principal application is as a full-wave power rectifier in equipment with vibrator type power supplies.
$3.90
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.
$3.90
Miniature, high-mu, twin triode designed for use as a radio frequency amplifier or as a combined oscillator and mixer in FM receivers.
$3.90
Miniature heptode primarily intended to perform the combined functions of mixer and oscillator in automobile radio receivers. Specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.
$3.90
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
$3.90
Miniature remote-cutoff pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers.
$3.90
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.
$3.90
Heater type vacuum twin diode using the lock-in construction. It is intended for use as a full-wave rectifier in either AC or storage operated equipment where economy of heater power is desired.
$3.90
Miniature pentode intended for use as a radio-frequency or intermediate frequency amplifier in automobile radio receivers. The tube is specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.
$3.90
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
$3.90
Miniature, duplex-diode, high-mu triode designed for use as a combined detector, amplifier, and automatic-volume-control tube
$3.90
Miniature double triode in the 9-pin miniature construction. Section #1 is intended for use as a vertical deflection oscillator having medium mu and section #2 is intended for use as a vertical deflection amplifier with lo mu.
$3.90
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.
