The Elrad plate was made of zinc plated sheet steel, 1.5 mm thick.

As transducer they used these thingies that were available back then
that were attached to wooden surfaces to form a "membrane-less"
loudspeaker. They were called "Echonic". As receiver they used two small
condenser microphones. They write that they tried
instrument pickups too (like a Barcus Berry Grand Piano pickup) but the
results were poor.
