Default dual secondary transformers

hello all,
so i am about to embark on building a lm3886 amp with a snubberized psu, however i am having some difficulty sourcing transformers with dual secondaries, and i wondered where everyone else out there was finding theirs. i'd appreciate any suggestions, thanks.

to begin, i should have mentioned that i am looking for toroidal transformers.

i have looked at partsexpress, and they do not have dual secondary toroids that i see.

Default ok, i may be an idiot

ok, i apologize for my ignorance. i do believe i have been misinterpreting just exactly what 18v+18V, 24v+24v, et cetera mean.

What is the advantage of a dual secondary transformer over a center tapped transformer?

What is the advantage of having a snubberized power supply over a conventional center tapped transformered supply?
