I think if you do a little looking you can find someone that can rewind your field coil. A replacement transformer shouldn't be a problem to find. If you do go with a PM speaker and a resistor instead of the field coil you will find that you will need to up the value of the filters to reduce the hum. The field coil or a choke will help filter the hum out much better than a resistor with less of a voltage drop.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
