This transformer is burned out. I have on hand a quiet power supply with the exact voltages I need. Where would I tap in to the 12.5 volt cuircuits and what should I remove?
My power supply has +/-12.5 volts dc
My power supply has +/-12.5 volts dc
You've provided little in the way of circuit details.
You might remove the old transformer and insert the new supply across the filter capacitors.
If the old supply was regulated, you could insert the new supply at the vreg outputs. You could cut a board trace there and not have to remove anything.
Sorry I can't be more specific.

Indeed, some more info is needed on the circuit you want to use it for.
Also ask yourself this question: why did the transformer burn out?
Having said this, +/- 12.5 VDC sounds like something you would use to power low power devices that need a symmetrical power supply, like opamps. If they were indeed originally fed by a regulated supply, I'd probably disconnect the original psu behind the regulators (desolder wires if they're on a separate board or take out parts or cut traces if they're on the same board) and feed in the new psu from there.
