Also, what are the odds I could try the speaker in my 40-180? This morning I just remembered it has the same shape connector. Assuming the field coil is on the same pins, would that work? It looks like the field coil on it has less resistance though (1100 in the 40-180 vs 2000 in the 39-30) and the voice coil grounds to the speaker frame in the 40-180, which it doesn't in the 30-39. That way I don't have to try and find a PM speaker probably burred somewhere in my parents basement and mess around desoldering anything.
