[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
