Using Texas NE5532, gold-plated IC socket, you can replace the other models according to their preferences op amp IC.
Wide voltage range, and after the rectifier filter capacitor used 2200uF/16V. 7812,7912 dual-power regulator, so that circuit more stable.
Coupling capacitor with the top Weimar capacitor 3.3uF.
Resistors use metal resistors, ensure the machine a good signal to noise ratio.
1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL whole process.
