These can fail over the years and give the impression of tweeter failure.

This happened to a pair owned by a friend of mine years ago, B&Ws advice was to simply bypass the suspect parts....and watch the volume.
Am I right in thinking that the Mk II versions had more sophisticated overload circuitry, which would shut down the overloaded unit and display a warning light in the tweeter housing until reset?
Is the Mk 1 version just fuse protected?
