In the circuit, Al gain is about 10 times, and the total circuit gain is about 30 times. Supply voltage is ± 35V. Al's power supply voltage is 13V, which is stabilized by VDz1 and VDz2 voltage-regulator tube from ± 35V. RP1 is used to adjust the offset voltage of A1. When the input voltage is zero, adjusting RPl can make the position is section start. If the input is connected to D / A converter, you can use digitto locate position.
