Default 0v wire on transformer

sorry yall, gotta a stupid newbie question.

im confused a bit on my transformer situation. this is for brians lm3886 pcb.

ok so my torrodal transformer has 3 wires going in. 5 going out. for the secondary orange + orange = 26.5v

and... yellow 18v - 0black - yellow 18v

my question is if im doing a stereo set-up would i run both yellow and orange to psb? and what do i do w/ the blk 0v wire?

sorry for probably the most basic question possible in electronics but im fresh and lost at this point.

oh yeah and why is there 3 going into the transformer? thanks

Hi,
three in !!!!
Five out is very probable.

You need to check what is IN and OUT and what are connected and what are apparently isolated.

Check again and come back.

I think he meant improbable! But they start very early on the whiskey in those parts at this time of year!

I meant it.

eg. V-0-V & V-0
or
V1-V2-0-V2-V1
or
V-0 & V-0 & screen.
any of these alternatives are valid outputs.

I'm on the point of giving up.

Do not attach the transformer to either the mains or your amp until you KNOW that it is connected correctly and that the voltages are correct.

Is orange connected to orange?
Is orange connected to any other?
Is black connected to any or all wires?
Is yellow connected to any other?
etc?
