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.
Vacuum Tube - 6K7G, Pentode, Remote Cut-Off, RF
The 6K7G is an indirectly heated pentode of the vari-mu (remote cut-off) type for use in the RF or IF stages of radio equipment.
