A 1945 78 rpm Gramaphone Record

In America in 1900, the two leading manufacturers of flat records were Columbia, which used 80 rpm as its speed, and Victor, which used 76 rpm. Since one company's records were playable on the other's machines, it is only logical that the eventual standard speed would be in the middle. By 1925, the speed of the record became standardised at a nominal value of 78 rpm. However, the standard was to differ between America and the rest of the world. The actual 78 speed in America was 78.26 rpm, being the speed of 3600 rpm synchronous motor (run from 60 Hz supply) reduced by 46:1 gearing. Throughout the rest of the world, 77.92 rpm was adopted being the speed of a 3000 rpm synchronous motor powered by a 50 Hz supply and reduced by 38.5:1 gearing. This 78 rpm record is a 1945 live recording at The Green's Playhouse, Glasgow by the artist 'Joe Loss and his Orchestra' Property of Robert Pool
