Woah! Just noticed that ninja-post just now! Sorry about that! That was the problem, I couldn't find any 22uF non-polarized capacitors. Hence the current situation of using a polarized 22uF capacitor and a 0.1uF non-polarized capacitor. Yes, that "mess" is easier for me to understand In case you don't know, I'm no engineering student, so A) I have no idea who to go with, since I have no idea what changing a part will do! B) I have no idea what you're talking about in your last paragraph! No, you're right, I have the positive side (the side with the stripe) pointing to the mini-DIN connector, because I thought that you're suppose to point capiactors towards the output? Ah, OK, so it should look more like this? Since I've rotated the DIP adapter, that means the polarized capacitor is around the wrong way now, right? So I should flip it around?
