We found this circuit in documentation from the 1980s. The transformer is of the low voltage type with a 1: 3 turn ratio and the transistors can be of general-purpose types.
Taking advantage of the high input impedance of the operational amplifier 741 and its high gain we...
This old circuit uses na operational amplifier not easy to find in these days. But the circuit can be...
This configuration makes use of an integrated circuit of the time having been found in a 1976 NASA...
