    With great difficulty, and using a LOT more specifications than you gave there!.

    What EXACTLY are you trying to do - audio transformers have mostly been 'designed out' of circuits for many decades, due to high cost, low performance, and almost impossible availability.

    I assume its something like this you want to make:

    But yes, it would be very difficult to make. I'm sure you can buy one like this where you are, or modify the circuit to not require it.
