There are guys rewinding, as a business, transformers in their basement up 
to the .5KVA level or so. I rewound the secondary of an AL-80 xfmr several 
years ago with reasonable success. That meaning I only had one lamination 
left over and the AC voltage was only about 75V low. Not a fun job as my 
prior experience was making big filament xfmrs from TV units.

In the 30's hams made their own transformers and chokes well beyond the KW 
level. Old QST's and Handbooks had how to articles.
