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.
T-6AU6A_EF94 Vacuum Tube - 6AU6A / EF94, Pentode, Sharp Cut-Off
