Step 20: Assembly Step 9: Capacitors

Picture of Assembly Step 9: Capacitors
Installing the capacitors works the same as for the resistors. We have 5 different types: C6 and C11 (ceramic, 47 pF), C14 and C15 (ceramic, 100 pF), C9 (electrolytic, 100 uF), C18 and C19 (trimmer), and 10 pieces of 0.1uF ceramic capacitors (not labeled because they are the only type left).
 

Note: Be careful when installing C9 – it has to be put in with correct polarity. The negative side of C9 is clearly labeled with a white stripe and “-” (minus) symbols – make sure you install it as shown in the pictures below with this white strip facing inwards on the PCB!
