This is a modern re-creation of the famous Thomas Edison Cylinder Phonograph. It was designed to allow historians and enthusiasts to play and digitally record wax cylinder recordings from the late 1800's using a modern modified stereo cartridge and stylus.
It features 2 independant servos to drive both the mandrel and stylus (wax cylinder not shown). The mandrel can also be fitted with optional adapters to play a variety of cylinder sizes.
Lastly, the phonograph features a custom designed control board that allows digital speed control, keeping the mandrel and drive screw perfectly in sync.
