How To Make an Audio Transformers?

[BlackSharK]

Hi,
     
    I found many applications of Audio Transformers in some of the schematics found in here and found them pretty expensive.I can't find them in local shops since they only have power supply transformers.Is there some particular power supply transformer that can be used as an Audio Transformer? (My country's power supply is 220V).Or else is there any source I can get knowledge on making one?

Thanks,
BlacK
