Capacitors question on simple booster circuit

[JackLondon]

Hi Guys,

I've just got into building stuff so please bear with me, I am reading a general idiots guide to electronics as I'm goin along. My first build is a kit for a simple booster and I have encountered a puzzling problem. I don't know which way I should install capacitors onto the PCB, I'm fairly new into reading schematics and it will probably help me to indicate it but at the moment I can't work it out so could any of you advise which is the correct option ?

Option 1


Option 2


Option 3




Here's the schematic http://diy.musikding.de/berichte/eff/daslineal/bilder/schemeng.gif


Cheers for any help, greatly apreciated

Options 2 and 3 are equivalent.  Either one will work fine.  I am not certain why they have the extra pads (the green ones in option 1). They are connected.  Perhaps it is to accommodate capacitors with different spacing of the leads.

You can follow this on the schematic.  R1 connects to ground and to C1.  The other end of C1 goes to a junction that connects R2, R3, and Q1.  That junction and the connections are the two green pads in your option 1 and the leads to the other components.

Option 1 has a short piece of copper across the cap. A short plus a cap is still a short. So why have a cap at all?

And if you follow the "IN" signal, all it does is warm a resistor, there's no connection to the rest of the mess. That's probably not how it should work.

2 and 3 work, and cover caps in two sizes. Unlike resistors, cap sizes and lead-spacings are all over the ruler.
