transformer with 3886 (BrianGT Boards)

hi all,
I bought BrianGT's dual mono 3886 boards, and bought a hammond dual secondary trafo. my newbie question is, should i have bought two of them? I mean, it seems that I should hook up both secondaries to each PS input, is that correct? Is there a way to 'split' the output of the transformer, or should i have bought two (i guess, thinking about it it may have made sense...doh)
thanks
