You need to tell us what DC output voltage you want and what's the maximum load current. Without that it's not possible to answer your question.

If you're going to power the α20s with ±12V rails, then the AN-0112 will work. Use one σ25 and one σ26 to get the positive and negative rails. The transformer has two secondaries, use one for each of the σ25 and σ26 regulator boards.
