 The Danish firm Ortofon provided the tonearm for the 927 (‘RF-297’) and the first magnetic pickup officially installed by EMT on their turntables.A stroboscope engraved around the acrylic outer platter allowed the fine tuning of the 927’s speed and its quick-start arrangement allowed a remarkably short starting time of less than 500 milliseconds at 33 rpm.The 927 was built in different versions, the ‘927A’, with an optical indicator of the position of the stylus on the grooves, the ‘927D’, a special reference version built with special care and very close tolerances for laboratory use, while the ‘927F’ could accommodate a second tonearm behind the platter, and ‘927st’ stereo version.
