I worked on one of these last year. There will be a lot of bad wiring in there. I disassembeled the IF cans and connected new wires. There are some shielded cables made up of rubber covered wire that disintegrates in a spring wire braid...I replaced these with coax cable like RG-59 and it worked great after re-aligning. We also made new knobs for it out of wood in our shop.
You can stick a PM speaker in there...just replace the field winding with a filter choke or the highest resistance winding of an old power or output transformer. You will probably need an output transformer too as it is on the speaker if I recall right.
