Hello all,

I've been looking all over the place and I can't seem to find any data on the inductance value for the field coil in the speaker. I have an RLC bridge but according to my ohm meter, the winding is no longer continuous. The speaker itself is beyond repair. I want to replace it but I need the inductance value for an equivalent value choke.

Thanks to all who can help!
Mike
