Ako su manje modifikacije u pitanju možda odmah tu oprugu zameniti tegom. Ovde ima i još kojekude...

"This is a (2011) modification, developed (and sold as a kit) by Jean Nantais, which replaces the internal spring. The Lenco spring facilitates the critical connection of the idler-drive with the platter, and Nantais replaces it with a hanging weight. The weight is intended to optimize the torque*, keep it consistent with different speeds (especially at 45 RPM**) and eliminate the varying tension of the spring, due to aging, usage and manufacturing tolerances."
