-6. **Solder in the four polymer capacitors.** Beware of their polarity, minus (-) is marked on the body and plus (+) is marked on the circuit board! Double check you are soldering them in correctly, it isn't easy to desolder them. You can use the photo as a reference.</WRAP>+6. **Solder in the four polymer capacitors.** Beware of their polarity, minus (-) is marked by the pink color stripe and plus (+) is marked on the circuit board!

-15. **Check one more time if all the polarities (chip, capacitors, battery connector, battery) are correct.** Reversing the polarity might irreversibly damage the circuit. Attach the battery and turn on the device with the potentiometer (it has a built-in switch!). 
- 
-16. **Check whether the LED lights up.** Plug-in your headphones, turn the potentiometer almost all the way up and **listen if you can hear the buzzing and humming of the electricity** around you from both channels.
