The pins of the IC are very thin , pins 3 to 10 must be doubled by 1mm thick wires solderd on alternate side by using a piece of sand paper isolating the pin while soldered . The wires to be long enough to reach destination along the pcb track .

This circuit requires double bridged amp. I have class A version of 2x LM3886 .30WATT class A Phoenician amplifier . There is also another one much older using offset bias.
