Hello everyone, this is my first post, but I’ve been reading and learning here for a while.  

I have decided to restore my 38-93 that belonged to my Grandparents, I imagine they bought it new.   I’ve had it for a non-working mantle piece for 25 years.
 I’ve been dabbling with electronics for a while, building stomp boxes and simple guitar amps for friends, but that is about the extent of my experience. This is my first tube radio and I’m completely addicted to working on it.  
I’ve spent hours mapping the chassis on paper, taking pictures identifying parts and making notes.
 Last night I got down to testing the resistance of the field coil and output transformer. According to the drawing (37-93) the field coil has an R of 1140Ohms and the output transformer has an R of 400Ohms.  I got no reading on either. Is this thing toast? Can they be re-wound? I would like to use this speaker since it’s the original if at all possible.
This is such a great site, I’ve already learned a ton of stuff I would have had a hard time learning otherwise.  Thanks in advance.
