Install U7, the motor driver for the balance and volume pots. As in previous IC
installation steps:
 Get the IC in the right way by matching silk screen and IC orientation marks
 Bend two corner pins to retain the IC until you solder it in place. Choose places to
bend the pins that avoid shorting traces together.
