This powerful high-fidelity amplifier was described in an article in Radio Electronics magazine in December 1973. Note the use of 8 high-power transistors that must be mounted on excellent heat sinks.
We found this circuit in a 1998 documentation. It tests common household appliances to see if they...
The circuit presented consists precisely of an oscillator (multivibrator) that takes advantage of the 4...
