Description
This is a rare Edison "Tuning Disc". It plays a continuous pitch of "International A" and using a pitch pipe a dealer/repairer could insure that the turntable was revolving at 80 rpm. This example has the paper underlabel with "Tuning Disc" ink stamped on it. I am including two original instructions, one for using the disc and one for adjusting the speed of a machine using the disc.
I am continuing to sell my 30 year collection of phonographs, parts, accessories, and records, so please bookmark me. All items are sent via Priority Mail with insurance and am happy to combine shipping.
