I picked up this old guy at the auction. http://www.flickr.com/photos/53710524@N06/10141888325/ It's a 1924 Crosley Trirdyn. Three tube that do the work of five. The circuit is a regenerative reflex. Anyway it seem like a interesting project and I think the price was about what the three good 01A's cost.
When I got it home I gave it a cursory checkout and found that both audio transformers are open. After a little research I found that AES sells the winding part of the transformer without the lamination. So the repair of the transformer just requires disassemble the laminations slip on the new core reassemble and it's done.
Also one of the tube sockets was broken. I used some epoxy to fix it. I do have a backup plan if the epoxy doesn't hold up, one of the Phorum member was kind enough to make one available to me.
Tomorrow I'm going to order the parts to rebuild the audios in this old guy. It also needs some serious cleaning!!
Here's the info on this set:
