Ortofon OM Scratch
Specificaties Ortofon OM Scratch
Scratching and back-cueing impose heavy mechanical stress on the cantilever and its rubber bearing. Therefore, the Ortofon disco cartridges are equipped with cantilevers made from aluminium tube with increased wall thickness. Special attention has also been paid to the attachment of the bearing and the design of the bearing itself. This means that rough treatment will neither damage the cartridge nor degrade its stability.
