# 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.

#### Peavey

Hartley Peavey founded Peavey Electronics, one of the world's largest manufacturers and suppliers of musical and professional audio equipment, in 1965, having built his first amplifier in 1957.

#### 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.
