How to make audio transformer ?

Can use 5 volt transformer

like your projects, but they lack detailed instructions... you mentioned copper winding wire (to make a audio transformer ) but how to make it and what gauge of wire required?

you can take a transformer from mosquito bat or CFL lamp

circuit with the same Gage of copper wire and wind primary 400 turns and secondary 40 turns following 10 turns
refer to the circuit diagram
