negative of the power supply, a negative supply required to track changes in the positive supply. Figure W7800 do with the positive supply, operational amplifiers and power tubes can be traced negative supply. Shown by two identical (higher precision) of 4.7 k resistor, the potential of the F007s control inputs at zero level, and the output of the F007 with the power to control the negative loop regulator to maintain the output of the negative positive output tracking. F007 op amp power supply with positive and negative input voltage source.
