# 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.

#### Apex Matched

Custom-designed and custom-built by industry experts with ideal tube matching in mind. Apex tubes are matched more closely and more accurately than you'll find anywhere else. Visit https://www.apexmatching.com for more information

#### Yellow Jackets

Yellow Jackets allows amplifiers using common power tubes to use EL84s without modification or rebiasing.

TAD is a German company established in 1993 which selects and matches electronic tubes and manufactures musical instrument accessories.

#### 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.
