This is the wonderful Bang & Olufsen MMC20CL Cartridge which I used sparingly on my B&O 4004 Linear Tracking Turntable and was always critically acclaimed by many reviewers and audiophiles. I had a cartridge on the 4004 and this MMC20CL was my extra. Before I recently sold the 4004 I installed this cartridge and set tracking force to 1gm. This cartridge sounds excellent with wide soundstage, sizzling highs, and a very smooth midrange plus both channels working. Truly one of the best sounding cartridges I have listened to. I was going to keep cartridge and install on other (non B&O) turntable but I would need an adapter to go to 1/2 mount and cost was over $150 so I am now selling cartridge. This MMC20CL is a very delicate cartridge with its crystal sapphire cantalever so I have decided to sell AS-IS for parts or repair for I need to protect myself from swappers or someone who breaks the cantalever. Please view my feedback and purchase with confidence. This cartridge is working, clean, and free from sag, I am sure this is one of the finer MMC20CL cartridges. Before you purchase be sure it will fit your turntable for there are no returns or refunds for any reason. This is the cartridge with connector that installs into top of cartridge and NOT like the MMC1-5 with contacts on back as seen in pictures. I will pack so cartridge arrives perfect and without issue. LAST NOTE I WILL REPEAT. CARTRIDGE SOLD AS-IS WITH NO REFUNDS BECAUSE OF SWAPPERS AND DELICATE NATURE OF THIS CARTRIDGE. IF YOU ARE NOT FAMILIAR WITH HOW DELICATE A CRYSTAL SAPPHIRE CANTALEVER IS PLEASE DO NOT PURCHASE. I will pack like you want it packed and ship by USPS Priority WITH SIGNATURE CONFIRMATION for a flat $15, this cartridge will not just be left in a mailbox.

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.

(english description at the bottom) Ich verkaufe hier einen wunderschönen, komplett revidierten und modifizierten Beogram 4004. Zu dem hier angebotenen Gerät: Der Beogram wurde technisch komplett überholt und optimiert. „Komplett“ heißt komplett. Das Gerät wurde vollständig zerlegt, alle mechanischen Teile gereinigt, poliert oder erneuert. Die Elektronik wurde ebenfalls vollständig überarbeitet. Sämtliche Kondensatoren und Widerstände sind neu. Alle Lötpunkte wurden nachgelötet, Plattenteller- und Motorlager gereinigt und mit feinstem Öl neu befüllt. Die anfälligen Festwiderstände der Steuerung wurden durch hochwertige Trim-Potis ersetzt, die Sensorik der Tonarmsteuerung auf LED umgerüstet und perfekt feinjustiert. Das Gleiche gilt für die Geschwindigkeitssteuerung. Dieser Beogram erkennt auch transparente Schallplatten und spielt diese anstandslos ab! Selbstverständlich sind die beiden Riemen ebenfalls erneuert. Zusätzlich wurde der Beogram mit einem hochwertigen RIAA Vorverstärker ausgestattet, der von einem Spezialisten in Dänemark entwickelt und hergestellt wird. Somit kann der Beogram an normalen Hochpegeleingängen betrieben werden. Die verbauten Module und Optimierungen stammen zum Großteil aus den USA von dem in der Szene sehr geschätzten Rudy Schlaf (beolover). Zur Optik: die Alupanele befinden sich in erstklassigem Zustand. Die Holzzarge wurde mit Echtholz in Palisander neu furniert. Die Haube (von Beoparts aus Dänemark) ist genauso wie der Zierstreifen aus Aluminium nagelneu. Es handelt sich um eine getönte Haube inklusive der Gummipuffer für die vorderen Ecken.Die Haube wurde in einem Stück gegossen (spritzgegossen). Sie hat keine geklebten Nähte!Diese Haube ist ein direkter Ersatz für die Original-Teilenummer 3164190 von Bang & Olufsen.Ich hatte das Gerät ursprünglich mit einer beschädigten Haube angeboten. Diese Haube hier ist wie gesagt neu! Dieser Beogram ist ein Traum, mit dem oben beschriebenen zusätzlichen Feature eines integrierten RIAA Vorverstärkers. Wer sind wir? Wir sind zwei B&O Enthusiasten, die die Restaurierung von alten B&O Geräten zum Hobby haben. Mein Techniker hat schon weit über 50 Beogram 400X restauriert und kennt die Geräte wie kaum ein Zweiter. Wir haben unzählige Arbeitsstunden investiert und alleine die Bauteile und das Basisgerät haben über 2500,-€ gekostet. Das gezeigte MMC 20EN ist in erstklassigem Zustand, klingt hervorragend und gehört zum Lieferumfang. B&O selbst bietet übrigens auch die Revision des Beogram 4002/4 an. Dort bekommt man einen neue Haube, eine neue Holzzarge, neue Kabel und Riemen und das Gerät wird geprüft und defekte Bauteile ersetzt. Preis bei B&O: 5000,-€ (nur für die Revision und Teile - der Beogram und MMC sind nicht im Preis enthalten und natürlich auch nicht der RIAA und die technischen Verbesserungen des von mir angebotenen Beogram). Hier nochmals eine Zusammenfassung der durchgeführten Arbeiten. Gehäuse: - Komplette Demontage des Beogram 4004 - Reinigung des Chassis - Erneuern der Haube - Holzzarge neu in Palisander (Echtholz) furniert Technik: - Neue Riemen für Plattenteller und Tonarmantrieb - Austausch der Glühbirne des Tracking-Sensors mit LED mit neuem Präzisionstrimmer statt Festwiderstand - Erneuerung der Beleuchtung der Drehzahlanzeigen 33/45 mit SMD LED - Austausch der Sensorarmbirne durch LED-Baugruppe inkl. Austausch des Transistors und Trimmers - Austausch des Drehzahl-Trimmers durch 20-Gang-Präzisionstrimmer - Austausch des Drehzahl-/Ausgangsrelais - neue Riemenscheibe für den Tonarmantrieb- Säubern aller Platinen - Nachlöten sämtlicher Lötpunkte - Austausch sämtlicher Elkos durch hochwertige Elkos - Einbau eines RIAA-Vorverstärkers mit integriertem Mutingrelais, entwickelt für die Beogram 4000 Serie - Überarbeitung von Motor- und Plattentellerlager Es handelt sich um einen Privatverkauf ohne Rücknahme. Da das Gerät vollständig neu aufgebaut wurde gibt es aber 1 Jahr Gewährleistung. Die Gewährleistung beinhaltet allerdings keine etwaig anfallenden Transportkosten! Das Gerät kann in Berlin Westend vorgeführt und abgeholt werden. Für dieses Exemplar lohnt sich mit Sicherheit auch eine etwas weitere Anfahrt! Versicherter Versand per DHL ist möglich, die Kosten sind wegen der aufwändigen Verpackung (box in a box) und des hohen Warenwertes aber entsprechend hoch (39,98 € innerhalb Deutschlands, 88,49 € innerhalb der EU).Bei Sofortkauf ist der Versand kostenlos. Auf Wunsch kann ich bei Sofortkauf den Beogram in einem Umkreis von 300 Kilometern von Berlin auch persönlich - ebenfalls kostenfrei - ausliefern. Bitte kontaktieren sie mich aber bitte vor dem Kauf, um einen Liefertermin zu besprechen. English Description: I am selling a beautiful and completely revised and modified Beogram 4004. About the device offered here:The Beogram has been completely technically overhauled and optimized. Complete means complete. The device has been completely disassembled, all mechanical parts have been cleaned, polished or renewed. The electronics have also been completely revised. All capacitors and resistors are new. All soldering points were resoldered, the turntable and motor bearings were cleaned and refilled with the finest oil. The vulnerable fixed resistors of the controller have been replaced by high-quality trim pots, the sensors of the tonearm controller have been converted to LEDs and fine-tuned to perfection. The same applies to the speed control. This Beogram also recognizes transparent records and plays them without any problems! Of course, the two belts have also been renewed. In addition, the Beogram has been equipped with a high-quality RIAA preamp, which is developed and manufactured by a specialist in Denmark. Thus the Beogram can be operated at normal high-level inputs. The built-in modules and optimizations come mostly from the USA by Rudy Schlaf (beolover), who is very much appreciated in the scene. As for the look: the aluminum panels are in excellent condition. The wooden frame was re-veneered with real rosewood.The dust cover (from Beoparts in Denmark) is brand new, as is the aluminum trim. It is a „smoked“ cover including the rubber buffers for the front corners.The dust cover was cast in one piece (injection molded). It has no glued seams!This one is a direct replacement for the original Bang & Olufsen part number 3164190.I originally offered the device with a damaged dust cover. As I said, this hood is new! Who are we? We are two B&O enthusiasts who have a hobby restoring old B&O devices. My technician has already restored well over 50 Beogram 400X and knows the devices like no other. We have invested countless hours of work and the components alone and the basic device cost over €2500. The MMC 20EN shown is in excellent condition and is included. B&O itself also offers the revision of the Beogram 4002/4.There you get a new hood, a new wooden frame, new cables and belts and the device is checked and defective components are replaced.Price at B&O: €5000 (only for the revision and parts - the Beogram and MMC are not included in the price and of course not the RIAA and the technical improvements to the Beogram I offer). Here is a summary of the work done.Housing:- Complete disassembly of the Beogram 4004- Cleaning the chassis- Renewal of the hood- Wooden frame newly veneered with real rosewood Technology:- New belts for platter and tonearm drive- Replacement of tracking sensor bulb with LED with new precision trimmer instead of fixed resistor- Renewal of the lighting of the rev counters 33/45 with SMD LED- Replacement of sensor arm bulb with LED assembly incl. replacement of transistor and trimmer- Replacing the speed trimmer with a 20-speed precision trimmer- Replacement of speed/output relay- new Pulley for threaded carriage shaft Beogram - Clean all circuit boards- Resoldering of all soldering points- Replacement of all electrolytic capacitors with high-quality electrolytic capacitors- Installation of a RIAA preamplifier with integrated muting relay, developed for the Beogram 4000 series- Revision of motor and turntable bearings This is a private sale with no returns. Since the device was completely rebuilt, there is a 1-year warranty. However, the warranty does not include any transport costs that may arise! The device can be demonstrated and picked up in Berlin Westend. Its definitely worth going a little further for this specimen! Insured shipping via DHL is possible, but the costs are correspondingly high due to the complex packaging (box in a box) and the high value of the goods (€39.98 within Germany, €88.49 within the EU). If you choose „buy it now“, shipping is free. If desired, I can also deliver the Beogram personally within a radius of 300 kilometers from Berlin - free of charge if you choose buy it now. However, please contact me before purchasing to discuss a delivery date.

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.
