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 - 7308 / E188CC, Dual Triode
Special quality double triode designed for use as cascode amplifier, cathode follower, etc. in RF and AF circuits.
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 - 7408 / 6V6GT, Beam Power Amplifier
Beam power pentode primarily designed for use in audio frequency power amplifier applications. The tube is a direct replacement for the 6V6Gt, but features additional controlled zero-bias characteristics.
