I reckon that you'd be well advised to have a close look at the underside of that strip-board and check the component interconnections. It is very easy to misplace a jumper wire or wire in a transistor the wrong way round. I've built many projects on strip-board and know just how easy it is to make mistakes like that. Look at it from this angle: it is a proven design, so provided the components were 'good' to start with and still are (bearing in mind what I've written above), I would expect that patience, persistence and perseverance will get it working.
