# 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.

#### Solid State Replacements

Solid state replacements for vacuum tubes are great for use for hard to find or costly vacuum tubes and for reducing 'sag' in power supply applications.

#### New Old Stock (NOS)

Our new-old-stock tubes were made by the major U.S. manufacturers, along with a small number of European manufacturers and are tested and guaranteed.
