Murf;
As long as the field coil, and the output transformer are good it should be fine to fire up the set, I assume you are going to hook up a test speaker to try it? The O.T transformer secondary doesn't have any real voltage across it, so as long as they are not shorted together I can't see a problem. If the spider and voice coil are still intact you could have a go at reconing the speaker, though I have noticed that console speakers don't seem to be that hard to come by. Someone was mentioning that many radio clubs end up with consoles donated to them, along with parts and other junk, so that may be another place to look.
