R30 = 3k3
one 2.2uf capacitor goes on the top side and has holes for it, its near the + next to the power header
another 2.2uf capacitor goes under the hef40106 chip. and is a thru hole capacitor, but is has to be solderd as a SMD capacitor on the bottom side, minus legg goes to where it says 1uf.. click on the image to have a closer look.
the two LED's can be solderd close to the PCB or with some distance to the PCB. what you prefer.
don't forget to clip off the small flap from the potentiometer, otherwise it will destroy the pot when you screw in the top pannel.
