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.

Consists of a triode oscillator and a hexode mixer in a common envelope. Reduces interaction between the oscillator and mixer sections and makes for stable operation in superheterodyne receivers on the high frequencies as well as the broadcast band.
