brain fart-how do I wire this transformer?

[Mbira]

I'm in the US. I connected the yellow and red together and the black and violet together for the primaries. I need +,-, and 0.

Do I connect Green to + Red and Brown to 0, and Blue to -?

I don't want to fry this accidentally.

The primary stuff is sound

Do I connect Green to + Red and Brown to 0, and Blue to -?

This sort of right in that Red & Brown will be zero, but at this stage you are still dealing with ac so green & blue will be ac & therfore swapping polarity with the freq of your mains. Therefore you can swap these connections to your bridge rectifier over & it will make no difference.

Tie red and brown together - this becomes a center tapped winding, 0V for a grounded center tap supply. Green and Blue each go to an AC terminal on the bridge rectifier for a full wave supply.

and then plus volts is derived from ground and plus rectifier terminal, and minus from minus rectifier and ground.

Ah yeppers guys. Thanks. Not sure what I smoked to get confused there...

Hey don't feel bad. I haven't had a puff in years and I spent about half an hour looking for a nonexistent utlility bill, thinking I had misplaced it and it was now past due. It took calling the company and talking to a representative to realize that I was thinking that 07/06/05 was June and not (per the American order of numerical dates) actually July 06, 2005, and hence that I hadn't received the damn thing yet!
