Hi "mister"
I think your speaker is a 12 inch unit? It is electrodynamic, with no audio output transformer mounted on it. It has an 860 ohm field coil, and either a 3 or 5 ohm voice coil - a quick look through my stuff does not reveal the exact specs on this speaker's voice coil, maybe Chuck has this info?
It could be replaced with a modern PM speaker, but (1) you would have to add a 850 ohm, around 25 watt, resistor under the chassis; and (2) original-type speakers are not that hard to find; in fact they seem to show up on our favorite online auction site (eBay) quite frequently.
Good luck,
