This is one of the channels of an amplifier suggested by Westinghouse in 1970s documentation. The circuit uses components from the era and no information about the transformer is given.
For bench use, this circuit functions as a bistable safety switch. The circuit is from a Radio...
The circuit shown is from Motorola's 1990 Linear Databook. Shaded components are optional. The...
We have here an ultra-simple amplifier stage of just one transistor, which can have some uses on...
