From our long experience of using profiled magnetic fields to stabilize and manipulate the AB phase boundary in superfluid He-3 in the zero-temperature limit, we have constructed a cell where we can place the AB interface in the vicinity of a pair of crossed vibrating wire resonators (VWRs). The VWRs provide sensitive mechanical probes of the A and B phase energy gaps and textures. Here we present preliminary results where we observe the dynamic response of the VWR at the AB interface.
