RONETTE CRYSTAL MICROPHONE TYPE B110 , 1950's

Popular microphone for the amateur in the 1950's the element is piezo crystal in spite of its low output, the plastic is Polopas, (trade name) which is a form of Bakelite. Price in the 1950's $13.50. Like Crystal cartridges these units have a high output voltage up to one volt peak.

Your comments:

• Did crystal mikes have a low output?
  As I remember, crystal pick-up cartridges had a relatively massive output compared to magnetic ones. (Crystal being more than a volt)
  Crystal cartridges also required no equalization having a pretty linear output.
