    Original Bang & Olufsen MMC20CL Cartridge/Stylus perfect working order Uk stock ready for dispatch NOW Checked on a spectrum analyser, delicate, accurate and precise matching perfectly to its published specificationTracking perfectly with 1gram vertical tracking force The first B&O cartridge to use a single crystal sapphire cantilever. 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lost and none added from extraneous sources.No cartridge will ever reach this ideal unless the Laws of Physics can be repealed.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. Any questions just get in touch, Id be glad to help.

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.

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.

    Bang & Olufsen Beomaster 6000, Beocord 6000 & Beogram 6006 See Description. Okay Ive tried to be as honest as possible with the photos Ive includes for this listing m, unfortunately I only 24 photos in which to do that. Should you wish for more photos or even videos of say the turntable spinning etc. Then Im happy to oblige. I will go through each unit below describing as honestly as possible: Beomaster 6000 This powers on A okay, there is no issues with the LED screen, a few scratches on it and the wood paneling has some chips but nothing major. The issue lays in the bars at the back has some bending on them as shown in photos. This can be bent back with some needle nose pliers. I started to do this myself but i dont have any needle nose pliers and was doing it with just a screw driver and didnt feel this was going to be the best way of doing it. So as Ive said the unit all works perfect but there is some bending on the bars behind as featured in the photos BEOCORD 6000 This all powers up and functions A okay, the screen LED works as it should. There is a tiny chip in corner which Ive shown in photos. BEOGRAM 6006 This unit powers up A okay. The needle moves to the table as it should. The turntable spons but is lightly catching at the moment. Unfortunately its missing the silver panel which you can see in the photos. This can be sourced easily if you want to purchase one. Ive tried to be as honest as possible with my description. But should you have any questions then please get in touch and Ill do my very best to answer them.
