How the Cylinder Phonograph Works

The wax cylinder was the first real commercial sound reproducer. Physicist and collector Bob Lillquist shows us an early wax cylinder machine developed by Thomas Edison (the 2 minute long cylinders with sapphire stylus). He shows us insides of the machine and gives us a basic tour of the cylinder phonograph. In our other videos see the later generation machines and more detail on wax cylinder creation.
