This circuit was originally designed with the operational 747 which is rare today. However, the circuit is valid for any operational that must be powered by a symmetrical source.
This high impedance and low capacitance buffer employs a junction FET that can be BF245 or...
Found in 1980s documentation, this amplifier uses a symmetric source and the gain is given by the...
