Made in Italy Goldnote Bobolino MC Phono Cartridge This is a used trade-in so I do not know its age nor hours. The Bobolino aluminum alloy light and rigid cantilever handles a precision Elliptical diamond for perfect structural rigidity. The cantilever suspension is made by a double elastic polymer inserted into a brass pipe to eliminate vibrations enhancing the best tracking ability. The Bobolino features a light dampened Delrin body having a mass of only 7.5 gram enables super vibration control and easy tone-arm matching both. Due to its 600 ohm impedance and 3.0 mV output level the Bobolino can be easily matched with any active phono preamp MM at 47 k? Please Note: to preserve the uniqueness all Bobolino cartridges have the serial number indelibly engraved on the cartridge body.
