What 2 outputs are you looking for? Do they share a common ground, or must they be isolated from each other?

hi there
welcome to the forums

You do understand that the transformer output is a 15V - 0V - 15V output
it HAS 2 outputs each one is 15VAC

the 0V wire is your common wire

Unless he wants 2 isolated outputs. Which is what I assumed when he is talking about cutting the windings.

Is it a transformer which acts as a voltage divider? Which is to say, is the supply voltage 30 volts, (voltage into the device) but (instead of using resistors in parallel as in a conventional voltage divider), the ratio of windings results in a split power supply comprised of three terminals.

One of the three terminals is +15v. The central terminal is zero volts and the third terminal is -15v?

I think you may already have two outputs, using a common ground (the central zero volt terminal). Check out whether the 15v outputs are respectively +15v and -15v using a multimeter. If so (subject to the views of more august entities here present) it may be you have two outputs already.

No, they're all AC.

yup possibly but he hasnt come back to confirm that ....

regardless, it would take little effort to split the loop that comes out onto the 0V terminal
and easily produce 2 separate windings. No digging into the transformer required

Sorry Steve. I understand now.
