[NJARC] field coil speaker replacement

Has anyone successfully replaced a speaker field coil with a resistor? 
I've read about people doing it, but never actually spoke to anyone who 
actually did.  (Perhaps it's something I'd find on Snopes)

I'm restoring a Zenith 5S-126, the small cube radio with a black dial. 
The voice coil is scraping and therefore the sound is seriously 
distorted.  Connecting another speaker to the secondary of the output 
xfmr sounds perfect.  However, substituting a resistor for the field 
causes audio distortion (B+ is still within range).  Not the same 
distortion as with the scraping voice coil.

In the meantime, might anyone have a 6" replacement speaker with a 2100 
ohm +/- field?  Or how about some hen's teeth?

Thanks,
Bill
