Jim, Hammond doesn't make a power transformer with two center tapped secondaries. Neither does Edcor. I would have to buy two. And then the 2.5 volt 6 amp winding in the main transformer would be wasted. Arlyn at Heyboer can build the one pictured above for about $45. And it'll be about the size of a small choke. Closest Edcor could come would be $15.38 x 2 plus $15 dollars shipping. Same price.
