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.
Combines two independent diode units in the 7-pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.
