Build inverting LM3886

The inverting LM3886

R7, R9, R10, R12, R14, R15-R18, R29, R31, R32, R34, R36-R38, R40, a wire at C10, C13 if you want the mute feature, C14, C16-C23, C32, a wire at C34, C37 if you want the mute feature, C38-C45, wire jumper at D2, D3, D4, wire jumper at D6, D7, D8, wait with IC4 or IC5, L1, L2. L1 and L2 should be around 1 µH in parallel with a 10 ohms resistor, 0.6 watts to start with. Maybe you will need 1-2 W but I don't think so. This filter may not be necessary at all. See comment here.

If you of some reason don't want to use DC-servo, omit the following parts: R12, R14, R15, R16, R34, R36, R37, R38, C16-C19, C40, C41, IC4, IC5.

A wire at R16, R38, capacitor in C12, C36 instead of wire jumper.
