The operational 714 (not the 741) is an old Raytheon type that is no longer common today. The circuit can be implemented with modern operational. The power supply must be symmetrical.
We find this circuit in the 80's own component manual itself. The characteristics of the circuit...
We found this amplifier with high input impedance and low capacitance, using FET, in a...
This circuit was obtained in a 1979 magazine, but it can be easily assembled today, as the...
