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 by the major U.S. manufacturers, along with a small number of European manufacturers and are tested and guaranteed.
The 12AU6 is a pentode amplifier having a sharp cut-off control characteristic using the miniature construction. With high transconductance, low grid-plate capacitance, it is intended for service as either an RF or AF amplifier.
