Something that caught me out with my beogram 1700. I set the tracking weight to 1.1 grams, I thought, and the stylus shot across the record. I’d actually set it to 0.11 grams. The calibration is in tenths of a gram. To get the 1.1 grams that the stylus needs, you set it to 11 (shades of Spinal Tap), i.e. one complete rotation of the counterweight plus one unit.
