We found this circuit in the 1977 RCA Solid State ICs. The circuit consists of a current amplifier with a gain of 1000. The supply must be made from a symmetrical source.
The power transistors of this 80's circuit should have at least 10 A current collector and mounted on...
The critical component of this circuit is the transformar. We found it in an 1980s documentation....
This circuit is from an Italian publication called Fare Elettronica from 1987. What we have is an...
