Online auction sites and retailers such as eBay.com and Etsy.com are very often good places to find antique electronics such as record players and phonographs. Prices vary depending on manufacturer and condition.
Record players date back to Thomas Edison’s phonograph, invented in 1877. It was the first machine in the world created to record sounds for playback. It had a grooved wax cylinder that produced sound when a stylus that moved over the grooves transmitted the sounds into a horn-shaped amplifier. Emile Berliner improved on Edison’s design by trading in the more expensive wax cylinders for cheaper-to-produce flat shellac records.
