dual secondary transformers

jesserparker · 12th January 2007, 04:37 AM

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.

A moderator should start a Power Supply FAQ thread and make it a sticky...

ok, i apologize for my ignorance. i do believe i have been misinterpreting just exactly what 18v+18V, 24v+24v, et cetera mean.
so correct me if i am wrong (still), but actually this (for instance) transformer:

is exactly what i need for a power supply along the lines of carlos machado's snubberized psu?

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?
