Sorry I have not had a chance to answer your email, so I will just answer it here.
The original tube socket was held in place by a cylindrical piece of metal with a flange on top to retain the tube socket. This has two slots in the top of it. Four tabs which protrude from the top transformer bell go through the two slots and were spread out at the factory to hold the cylindrical piece in place, which in turn holds the rectifier tube socket in place.
You can gain access to the wires as soon as you remove the cylindrical piece and the tube socket. WARNING - the wires are cloth-covered, but the insulation will disintegrate once you start messing with them. I do think that removing the top bell (cover) is a good thing to do, once you have removed the tube socket. Then you can resleeve the wires with heat shrink tubing before reattaching a tube socket.
The tube socket that will fit the best is one from a 1937-38 Philco power transformer, as they were made for the purpose (proper fit and all). Any octal socket from any 1937-38 Philco power transformer will work; the sockets themselves (as well as their cylindrical keeper sleeves) are all the same size, I believe.
Advice? Find a donor chassis to obtain the proper tube socket (and cylindrical sleeve if yours is missing). Carefully remove the old tube socket; don't move those wires any more than you have to while unsoldering the wires from the old tube socket. Remove the top bell (cover). Resleeve the wires as their insulation will crumble once you start messing with them. Good luck...you'll need it. Yes, you can do it, but you will have to be careful and patient.
