Hrecord Turtle’s 78 RPM Jukebox is a huge collection of popular Victor, Edison, and Columbia recordings in MP3, from 1900-1930. They also have techtidbits like: “N.K. captured this selection at 78 rpm and electonically slowed it to 71 rpm for our enjoyment. N.K. uses a Technics SL-1900 turntable (modified to spin at 78 rpm ± 10%), a Grado F1 cartridge and a 3 mil conical stylus tracking at 3 grams. N.K. uses Sound Forge version 5.0 and Audio Cleaning Lab version 3.0 digital processing software”. [via] Link.
