We found this circuit in an old documentation, but the components used offer no difficulty in obtaining it. The CMOS integrated circuits are powered by a 6V supply.
We find this conventional amplifier with complementary transistors in a 1987 documentation. The circuit...
This circuit was found in a Poptronics of the 90's. The circuit limits the load current to 0.6 A....
This experimental circuit is from a 1975s publication. The coil consists of 80 turns of wire AWG...
