We will follow soldering the film capacitors (the rectangular ones). Start with the
10n (103) and continue [82n (823), 100n (104), 220n (224) & 330n (334)]. Then we
will solder the 4 diodes. Note that the diodes have an orientation marked with a
stripe that's also on the PCB.
Solder the electrolytic caps. These are the cilindric ones. But we will solder these
ones to the rear part. Take in mind that these capacitors are polarized, so you
must respect the orientation. The long led corresponds to the positive "+" side.
The negative "-" side is also marked with a visible white line.
