Germanium and silicon transistor output stage audio amplifier
This "mixed breed" amplifier was used in a Magnavox console stereo in the late 60's when there were PNP power germanium and NPN power silicon transistors at reasonable cost. I thought it would be interesting to investigate this amplifier circuit and replicate it on the breadboard.
