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 - KT88, Valve Art
Octal power tube (Max Plate Watts = 42W).
Starting at $40.92
Vacuum Tube - 6LB6, Beam Power Amplifier
Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. Very low knee voltage, high plate-to-screen ratio, and high peak current capability.
Vacuum Tube - 1L6, Heptode
Miniature type pentagrid converter designed for use in low drain battery operated receivers.
Starting at $40.65
Vacuum Tube - 6V6 C, Groove Tubes, Matched Pair
Octal power tube (Max Plate Watts = 14W) Classic design and affordable. Warm overdrive and soft distortion character. The 6V6 is a low-output power tube (12 - 18 watts) often used in Fender® amplifiers, including the Champ®, Deluxe™, Dual Professional, Vibro-King®, Princeton®, Vibrolux® and others. It has a very warm, round and soft response with rich harmonics, and distorts easily. One of the best choices ever produced for rehearsal and recording amplifiers.
Vacuum Tube - KT66, JJ Electronics
A sonically faithful reproduction of the original tubes with a robust construction encased in a thick glass envelope. The JJ KT66 delivers a powerful 25 Watts with plenty of headroom.
