The 4Point 14 inch tonearm just fits the Stabi M turntable with the use of a 12 inch cutout but some parts of the tonearm come very close to the edge of the lid. Please follow these instructions when mounting the 4Point 14 inch tonearm and cartridge.
To fit the tonearm on a Stabi M you need to change the distance from the spindle to the horizontal bearing. The standard distance is 340 mm and this must be changed to 338 mm so that the closed lid does not touch the tonearm. When the cartidge’s geometry is adjusted the protractors will automatically compensate for this change. This change in effective length is minor and not important ( just over 1%)
As the headshell with cartridge comes very close to the front of the lid, especially when the lid is half closed, slowly close the lid at first and check if the edge of the lid passes in front of the cartridge. At the same time check that the counterweight shaft at the rear of the tonearm is not touching either the back or right side of the lid.
