This circuit was originally intended to operate with a solar source for experiments. Transistors are general purpose, and the output current is relatively low.
This circuit is from a 1976 documentation. It makes use of isolated gate MOSFET which is already very...
This simulated circuit uses a 741 (Operational Amplifier), but other operational amplifiers can be...
In fact, what this circuit does is work the two channels of a stereo system producing two...
