Bang & Olufsen MMC 4 cartridge with integrated needle. Was used in the last series of record players. This MMC 4 is provided with a new elliptically cut diamond needle tip, and meets B&O specifications, the housing is original B&O. The rubber suspension has also been renewed. An advantage of installing a new needle tip is that you do not pay for manufacturing a cartridge with needle, but only for mounting a new diamond needle. I have this done by a renowned German company that only handles B&O needles. Hereby, the original cartridge is reused, because a cartridge is indestructible, and the quality is stable, this is no problem sound-wise. An additional advantage is that the original cartridge looks better than the aftermarket-which also meet the B&O specs however. 2-year warranty, except of wear and breakage.
