PROCEDURES
1. Solder the components according to the part list. Notice the polarities of the
electrolytic capacitors CP1-4 and CP1B-4B. There is no polarity of the thin
film capacitors.
2. Apply DC voltage +15V and -15V to connector labeled with VCC and VCC-,
respectively, without plug in the opamp U1 and U2.
3. If everything is ok, plug back the opamp U1 and U2 and apply input signals.
