Get yourself the originalSingle crystal sapphire cantilever offers a very rigid but light structure five times stiffer than aluminium and 21% stiffer than beryllium transferring more of the signal from your vinylEffective tip mass is a very low 0.3mg which ensures low record wear and a high stylus resonance well beyond the audible rangeThe body itself forms an effective Mu-Metal screen against stray hum fields practically eliminating magnetic interference Courtesy of Beoworld.orgMMC 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 records 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lost and none added from extraneous sources.No cartridge will ever reach this ideal unless the Laws of Physics can be repealed.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&Os 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 discs 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.

Please message me for that serviceTESTIMONIALS MMC6000 Manufactured: 1974 - 1979 Designer: Subir Pramanik Colours: Silver Bang & Olufsens (then) most accomplished pickup cartridge was fitted to Beogram 6000. The MMC principle was adapted to track 4-channel records: both Quadradiscs and SQ. MMC 6000 would track both mono and stereo records with the utmost fidelity. It was designed for record-players with tangential arms. The stylus was the Pramanik diamond, named after its inventor: engineer S K Pramanik from Bang & Olufsens Laboratories. The diamonds radii were 7 um/2 x 50 um. It was a refinement of the elliptical shape, rather like the shape of the cutter-head, and enabled greater contact with the undulations of the record groove. The cantilever was made of berylium - a material which is harder yet lighter than popularly-used aluminium. Effective tip mass was 0.22 mg. Compliance was higher than 30x10-6 cm/dyne. Recommended- stylus pressure was 1g. The total frequency range was 20-45.000 Hz. In the audible range: 20-15.000 Hz there is less than 1.5 dB variation and in the inaudible range 20,000-45,000 Hz where the carrier frequencies lie, the pick-up fulfils RCA/JVCs specifications for a Class A discrete 4-channel pick-up cartridge. Each cartridge is an integrated, individually calibrated unit. The stylus unit is not separately replaceable since it is part of the integrated unit. An individual frequency response curve traced on a Bruel & Kjaer level recorder and a complete Calibration Card were enclosed with every MMC 6000 sold.MMC6000 Product Specifications Pramanik diamond Radius of curvature CD-4 quadro Frequency range 20 - 15000 Hz+/- 1,5dB 20 - 45000 Hz (CD4) Channel separation 1000Hz >25dB 40 - 10000Hz >20dB Channel difference <1,5dB Intermodulation <1% Recommended stylus pressure 1g Compliance 30 x 10(-6)cm/dyne Effective tip mass 0,22mg Output mV/cm/sec. 0,6mV/47kOhmsWORLDWIDE carriage may cost more OR LESS!! than the listing states (I have to enter an estimated figure) and will be charged in full as per the service chosen and destination country.

beogram 4000 /tangential Turntable Bang Olufsen. Seem working well , in good esthetic conditions. Sold without a cartridge. For an international shipping please ask before buying

B&O Beogram 4000 Vinyl Record Turntable with MMC20E Cartridge This one is in good used example with some marks from normal use and storage but definitely nothing at all major and nothing that would affect its performance has recently been checked and tested - all works and sound good (see photos/video) there are some small knocks to the wood surround and the dustcover does have some marks that might be polished out but it does do its one job - protecting the turntable, the turntable is fitted with RCA phonos and separate earth wire and has hade a new drive belt fitted recently, and it comes complete with the B&O MMC 20 E cartridge/stylus, it is fitted with a 2pin EU plug with an adaptor to a standard three pin UK plug. Note: Collecting in person (from North London) is highly recommenced for this item or partway meet, at cost and by prior arraignment. UK delivery or shipping with ebay’s global shipping program also available. If you wish to send your own courier company to collect (or export) there will be a charge of £20 to cover full packing.

Bang Olufsen /B&O -beogram 4000 /tangential Turntable. Been in storage for some time and it won’t power on. It’s beyond my capabilities to diagnose any problem so is sold as seen. It also requires a stylus. Cosmetically it’s in nice shape the lid only has very minor scratching. The metal work and wooden plinth is also good order with only very minor marks. It would benefit from a good deep clean and a service, as stated it has been in storage for a number of years. It weighs a tonne so that’s the best I can do with postage but it will be insured for peace of mind. It will be shipped with care and to the best of my ability.
