Hi:

I just acquired a Radiola 18... I have a grasp of how it works but have never seen a speaker like the one that came with it.  It appears to have a permanent magnet ("U" shaped), and has some kind of transformer (I believe) mounted on the frame and has what I believe is an actuator coil for the cone.  Can anyone tell me what the components actually are and how to test them?  The cone is completely destroyed but I hope to make one if the electrical components are OK.

Thanks- Tom

I wanted to add that I have found info on the R-100A loudspeaker... but in the interim before I get my speaker repaired can I use an output transformer with the Radiola 18 to drive a new PM speaker?  If Yes what is the impedence of the primary?

Thanks- Tom

Yes 

Yes, a couple thousand ohms would be fine but it's not critical.
