Solid State Guitar Amp Forum | DIY Guitar Amplifiers

hey guys!

ok, so i'm trying to build a stereo lm3886 guitar amp, as for the transformer i bought this:
http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=122-615 (http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=122-615)
got it in the mail today, but i had a question about it  (i couldn't see anything about it in the formum, so i appologize if this question has already been addressed):
the transformer appears to have 4 mains and 4 secondaries, which is new to me. just thought i would ask you guys before i ruin something. i plan on building a ps like this:

so here go the embarrasing questions:

do i connect both sets of mains? why 2 sets of mains?

i'm assuming that the "0v" secondaries connect together, is that right?

thx in advance for any help and thx joecool for inviting me to the forum!
