/diy/ - Do It Yourself

I'm trying to build the circuit (pic related).

The closest audio transformer I was able to get hold off is the one I will post in the next picture. They're slightly different but I'm pretty certain it should work as a substitute.

The data sheet for the transformer I have (see next pic) shows which pin is which and how to use them in a 5 pin or 6 pin configuration. From the circuit diagram, it seems I need a 5 pin configuration, however, the pin missing would be pin 2 on the transformer whereas the data sheet only shows a 5 pin configuration for pin 5 being removed (which is on the secondary, not sure if I can just decide to flip the transformer around). How should I match the pins on this transformer to the circuit diagram? At the moment I've got it wired as the data sheet shows for an all 6 configuration but with pin 2 left floating.

Also, where do I connect the emitter of transistor Q2? It shows it going to -9v which I assume is the same as the line coming from the battery via the switch though the diagram shows that as +9v even though the battery is connected with a reversed polarity. Can someone please clear that up for me?

Thanks
