[Boatanchors] voltage on the speaker???

[jeremy-ca]

Thats a 70 Volt line speaker that is part of a shipboard 
intercomm/announcement system. Fairly new so it is PM.

A fast and fairly accurate way to determine the speaker imperence is to 
measure the voice coil with an Ohmeter and multiply by 1.3. The transformer 
must be disconnected.
