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 - 6AN8A, Triode, Pentode
Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.
Vacuum Tube - 3Q4, Pentode, Power
The type 3Q4 is a miniature type power-amplifier pentode designed for use in the output stage of battery operated equipment.
Vacuum Tube - 6MJ6, Beam Power Pentode
Novar type beam power tube used as a horizontal-deflection amplifier in color and black-and-white television receivers.
Vacuum Tube - 7199, Triode, Pentode
Triode-pentode designed primarily for high fidelity audio applications. The pentode section is particularly suited to preamplifier service while the triode section is intended for use as a phase inverter.

Vacuum Tube - 6LR8, Triode, Pentode
Triode-pentode containing a high-mu triode and a beam pentode. The triode is designed for service as a vertical-deflection oscillator, and the pentode as a vertical-deflection amplifier in television receivers.
Vacuum Tube - 6GW8 / ECL86, Triode, Pentode, Power
High-mu triode sharp-cutoff pentode
Vacuum Tube - 6AH6, Pentode, Sharp Cut-Off
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.
Vacuum Tube - 12BA6 / HF93, Pentode, Remote Cut-Off
Pentode amplifier having a remote control grid characteristic and utilizing the miniature construction. As a RF amplifier, it is characterized by high transconductance and low grid-plate capacitance.
Vacuum Tube - 6AU6A / EF94, Pentode, Sharp Cut-Off
Miniature sharp cutoff pentode primarily designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. Its low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications
Vacuum Tube - 3V4 / DL94, Pentode, Power
Miniature power amplifier pentode designed for use in the power output stage of compact, battery operated equipment. It is particularly useful in three-way portable receivers which employ 90-volta batteries.
Vacuum Tube - 8068, Pentode, Beam
Beam pentode designed for use as a series regulator in high-voltage power supplies.
Vacuum Tube - 7H7, Pentode
Semi-remote cutoff pentode using the lock in construction. IT is designed for use as an RF or IF amplifier.
Vacuum Tube - 6EA8, Triode, Pentode
Miniature tube which contains a sharp-cutoff pentode and a triode in one envelope. Each section has a separate cathode and is electrically independent. Primarily intended as a combined triode oscillator and pentode mixer in television receivers.
Vacuum Tube - 1LB4, Pentode, Power
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.
Vacuum Tube - 6SS7, Pentode, Remote Cut-Off
The 6SS7 is an RF pentode which as remote plate current cutoff. It is suitable for operating with AVC in Rf and IF amplifiers. The use of this tube will reduce cross modulation effects.
Vacuum Tube - 6J7GT, Pentode, Sharp Cut-Off
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
Out of Stock
Vacuum Tube - 6AZ8, Triode, Pentode
Medium mu triode and a semi-remote cutoff pentode in the 9 pin miniature construction. It is intended for general purpose applications in both monochrome and color television receivers.
Vacuum Tube - 12GN7A / 12HG7, Pentode, Sharp Cut-Off
Miniature, sharp-cutoff pentode designed primarily for video amplifier service in television receivers.
Vacuum Tube - 6BA6 / EF93, Pentode, Remote Cut-Off
Miniature remote-cutoff pentode primarily designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. Features include small size, low grid-plate capacitance, and high transconductance
Vacuum Tube - 42, Pentode, Power Amplifier, ST Glass
42 is a pentode amplifier designed for application in power output stages of receivers
Starting at $15.80
Vacuum Tube - EL34 II, JJ Electronics, Pentode
A different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. The JJ EL34 II is stronger than the original but not harsh sounding in any way.
Starting at $16.00
Vacuum Tube - 6AK5 / EF95, Pentode, Sharp Cut-Off
Miniature types used as rf or if amplifiers especially in high-frequency wide-band applications at frequencies up to 400MHz.
