Description
Preserving the Legacy of an Edison Disc
This is the C-19 model, the Chippendale. Produced between 1914 and 1924, these models were known for their intricate designs and expensive production costs.
Unlike the Victrola, the Edison Disc Phonograph played records with grooves that modulated up-and-down, tracked by a permanent diamond stylus. To avoid patent infringements, Edison implemented a gear-drive system that added complexity and cost to the manufacturing process.
