Default Power Supply

Hey Guys,
Where can i find information on older hammond transformers and chokes??
i have a power transformer reading;
AO-20927-3

One output transformer;
AO-16681-6

One choke choke
AO-16682-2
Well, i am tryng to add a gain stage into a hammond AO-44 that i have.
I read thru AX84 site and found some really helpful stuff one the design of the rest of the amp but i cant find any useful information on designing some power supplys... i try modeling some with PSUDII but i am having trouble figuring out some values and i rather stick to pencil and paper....where can i find a guide to design power supplys? i went thru the newbie section but most of them dont cover about it....
