research and the modifications that you suggested. The problem is that the
transformer has 6 legs and in the plans there are four legs, which legs
should I use or what do I do with the other two.
Thanks for posting your question here.
Ignore the center terminal on each side of the transformer. The center terminals are center taps, where, if the circuit required it, you could pull half the voltage. They are for stepping up or stepping down the voltage. You don't need to do this. Therefore use the two outside terminals on each side of the transformer.
Is this clear? Are you using the transformer I specified from Digikey? Note that the answer above will be the same regardless of the brand.
