Step descriptions:
✦Step 1:-Here are all the part we need:
✦Step 2:-Install all the parts on the PCB board.
✦Step 3:-Backside, cutting the rest pins.
✦Step 4:-Apply liquid flux before soldering.
✦Step 5:-Now soldering and wash with thinner after soldering.
✦Step 6:-The board is ready and attach the heatsink.
✦Step 7:-Mark the position for holes, make holes and apply compound on ICs.
✦Step 8:-Attach the knob for volume controlling.
✦Step 9:-Attach the speaker socket.
✦Step 10:-Connect the transformer, it is a 13-0-13 volt, around 1.5 ampere.
✦Step 11:-For connecting the phone, let’s connect the aux cable.
✦Step 12:-We have two 10ich subwoofer columns, and connect it.
✦Step 13:-Then connect the phone, and play.
