Once you are done with soldering all resis-
tors, your PCB should look like this:
Next, insert & solder the electrolytic
capacitors.
Electrolytic capacitors are bipo-
lar, and you need to mind their orientation.
The positive lead of each electrolytic capaci-
tor is longer, and there is a minus stripe on
the side of the capacitor’s body to indicate
the negative lead. On our PCBs, the positive
pad for the capacitor has a square shape,
and the negative lead should go into the pad
next to the notch on the silkscreen.
