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.
Vacuum Tube - 6C5GT, Triode, Medium-MU
General purpose triode designed for service as an oscillator, detector, or amplifier. It is similar in characteristics to the 6C6, 6J7, and 57 with triode connection.
