Step 7: Biulding the amp part 5

Next, on the other end of the amp (pins 4 & 5) you need to position your 220uf electrolytic capacitor where the positive (+) side lines up with pin 5 and super glue it to the side of the amp and the pot

Bend pin 5 over the cap's lead and onto the belly of the amp chip, then solder

Then solder a 5 inch piece of wire to the clearly marked negative (-) side of the cap, this is our audio output

FInally bend pin 6 of the amp chip up against the pot, this is our power + (pin 2 being ground), and get a 5 inch length of wire (I suggest red since this is power in) and, tin the pin, tin the wire and reflow together into a secure connection
