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 - 6W5-G, Rectifier, Full Wave
New Old Stock 6W5-G. Full-wave high-vacuum rectifier.
Vacuum Tube - 7027-A, Tetrode, Beam Power
Beam power tube for high-fidelity audio-amplifier applications.
Vacuum Tube - 7119 / E182CC, Dual Triode
The 7119 i a special quality double triode designed for use in computer circuits.
Vacuum Tube - 7189, Pentode, Beam
New-Old-Stock (NOS) tube. The 7189 is a power-amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and high-fidelity amplifiers. It differs from the 7189A in having a lower screen-voltage rating and no internal connections to pins 1 and 6. It cannot be used as a replacement for a 7591A in most situations.
Vacuum Tube - 7355, Beam Power Amplifier
Beam-power pentode primarily designed for use in the power output stage of high-fidelity audio-frequency amplifier systems.
Vacuum Tube - 81, Rectifier, ST Glass
Half-wave high-vacuum rectifier which may be used with either choke or condenser input to the filter.
Vacuum Tube - 813, Beam Power Amplifier
General-purpose transmitting beam power tube of the thoriated-tungsten filament type designed for use as an rf power amplifier and oscillator as well as an af power amplifier and modulator.
Vacuum Tube - 8233 / E55L, Pentode, Power Amplifier
Special quality pentode designed for use as a wide band output tube.
Vacuum Tube - 829B / 3E29, Dual Tetrode, Beam Power
Twin beam power tube
Vacuum Tube - 841, Triode, Power Amplifier
The 841 is an RF power amplifier, oscillator, and AF voltage amplifier.
Vacuum Tube - 8SN7GTB, Dual Triode
Medium-mu triode intended for use as a combined vertical oscillator and vertical deflection amplifier in 450 mA. series heater operated television receivers.
