BANG OLUFSEN MMC20S STYLUS CARTRIDGE B&O BEOGRAM 2400, 1102, 1100 1700 4002 4004 Tested and working Good used condition

Beogram 1700 turntable with MMC 20E cartridge. Used but both cartridge & turntable work great. Dustcover has some scratches as shown in the pictures. I’ve had this a long time- it was my first “serious” turntable. I no longer have the original packaging, but it will be packed securely for shipping. Local pickup is preferred- turntables can be sensitive to ship. Selling only because moving to a smaller place & thus forced to downsize. This was taken from a working vintage system that is being dismantled. My loss, your gain?

Original Bang & Olufsen MMC20S Cartridge/StylusUk stock ready for dispatch NOW  Checked on a spectrum analyser, delicate, accurate and precise matching perfectly to its published specification Tracking perfectly with 1.5gram vertical tracking forceTested on a Beogram 2400-2 and 4002 and sounds crisp and clear on both channelsThe model replacement for the MMC3000Matches black systems like the Beocenter 3600 - available with a cartridge in my other listings giving you the look of the original systemKeep playing your vinyl in the manner it was meant to be heardLow Effective Tip Mass protects your most precious vinyl from wear and damage  Courtesy of Beoworld.org MMC stands for 'Moving Micro-Cross'; the patented moving-iron principle upon which all B&O cartridges were based. This unique system employed a cross-shaped armature which, among other advantages, guaranteed exceptional stereo separation since each channel moves on a separate axis. The job of any pickup cartridge is to transform the record's physical profile (groove modulation) into corresponding electrical signals (which are then amplified or enlarged by the amplifier and turned into audible sound waves by the loudspeaker. A cartridge must perform three separate and exacting tasks if it is to do this job successfully. It must function mechanically (the movements of the stylus in the groove); it must function magnetically (using the physical movements to create changes in a magnetic field); and it must function electrically (using the changes in magnetic flux to generate an electrical current). At each stage, one type of energy is transferred into another, quite different, type. And the transfer must be perfect, with no energy lost and none added from extraneous sources. No cartridge will ever reach this ideal unless the Laws of Physics can be repealed. However, by understanding the relationships between the three transfer stages and continually applying refined engineering techniques, B&O's belief was that each stage of cartridge improvement would bring each successive cartridge closer to the ideal. Record wear and the cartridgeIf you take music seriously the value of your record collection is likely to be high. Many of your records are likely to be irreplaceable. You will also know that the signals pressed into your vinyl discs are very fragile indeed. The pickup cartridge can be the disc's worse enemy since an ill-suited cartridge can mark a record for life in a single play. While B&O is aware that cartridge specifications are inter-related, their research shows consistently that Effective Tip Mass (ETM) is one of the major factors affecting record wear. ETM is the equivalent of the amount of inertia the groove 'sees' in moving or accelerating the stylus tip. Consequently, the higher the ETM value, the higher the force required for a given constant acceleration. Obviously, more force results in more wear. Three elements contribute to ETM. The stylus tip (diamond) contributes with its entire weight and mass. The armature contributes between 5 - 20% of its weight and mass; the cantilever around 30%. B&O has been able to reduce ETM substantially by refining these elements and building them into an integrated unit. The result is a system which not only reduces damage to the groove walls dramatically, but also provides exceptional performance at all frequencies. This was the last of the MMC 20 range to be discontinued with cartridges being available late into the 1990s. It produced a typical warm B&O sound though lacked some of the more expensive models treble clarity. With an ETM of only 0.5mg, it was a fine cartridge and sturdy with it. The company’s range of MMC cartridges were integrated units, combining both stylus and cartridge as one slip-on unit. Matched, balanced and sealed in the factory each unit was meticulously computer tested with its results printed off and offered to the customer at time of sale. The printout included such information as output voltage, relative voltage output (channel balance), channel separation and frequency response. Manufactured: 1979 - 1985 Designer: Jacob Jensen Colours: BlackMMC 20 Cartridges Prior to the release of MMC1 - 5 cartridges, Bang & Olufsen had the following MMC range of combined styli and cartridges: MMC 20 S is a stereo cartridge with a spherical framed diamond

B&O Beogram 1700 Mit MMC20S / Plattenspieler Bang & Olufsen Ich Verkaufe hier einen Beogram 1700 mit MMC20S System der Marke Bang & Olufsen. Der Beogram funktioniert Vollautomatisch und spielt Platten in 33er, sowie 45er Geschwindigkeit ab. Durch Druck auf die entsprechende Taste bewegt sich der Tonarm automatisch zum Plattenanfang und setzt die Nadel in die Rille. Der Beogram ist bis auf ein paar kleinere im Licht erkennbare Mängel noch super erhalten und läuft sehr ruhig. Im inneren des Plattenspielers wurde die Mechanik gereinigt und bewegliche Teile frisch geölt. Die Nadel sowie das System funktionieren ebenfalls und hatten über meinen angeschlossen Verstärker einen sehr schönen Klang. Ein gut verpackter Versand ist auf Risiko des Käufers möglich. Für weitere Fragen stehe ich auch gerne zur Verfügung! Der Verkauf erfolgt unter Ausschluss jeglicher Sachmangelhaftung. Die Ware wird unter Ausschluss jeglicher Gewährleistung verkauft.

It was fitted to Beogram 4002. The stylus was an elliptical naked diamond, radii 5x17u. Recommended tracking force was 1g. Each MMC 4000 was designed as an integrated unit.
