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.

New Old Stock (NOS)

Our new-old-stock tubes were made in the U.S. by the major manufacturers, with several types made in Western Europe or Japan. All NOS tubes are tested and guaranteed.
