Description: Set of TWO unused crystal microphones. Great for radio and electronic project experimenter use, vacuum tube circuits, anywhere a high impedance microphone is required. Unusual and hard to find item. We have no technical for them. All elements are tested for normal, consistent output with an oscilloscope. These elements have lower output than larger sized elements. They must operate into a high impedance load. Elements measure 'open' on the 60 Megohm DC resistance scale of a DMM, which is normal. Plastic case measures 7/8 inches in diameter, 7/16 inches thick. Has 2 leads attached as shown.
