When I builds the circuit Pre tone control by IC LF353 the finished , but can not be usable. Because of it wants a power supply +15V GND -15V at 500mA current. I pairs then builds the group Dual DC power Supply +15V,GND,-15V. By use pillar equipment be IC 7815 , for +15V and IC 7915 for -15V. Which IC the bilateral can give currrent get about 1A. Other detail both of the circuit and model PCB you can see to follow a image.
