BITTE GENAU LESEN !Beogram TX inkl. MMC4-System Tangential-PlattenspielerDer Plattenspieler ist grundsätzlich funktionstüchtig. Selbst das MMC-4System klingt in meinen Augen noch gut (siehe Video, Plattenspieler ist allerdings nur an einem alten Beosystem 10 angeschlossen).Allerdings setzt die Nadel manchmal (nicht immer ?) etwas zu früh auf und der rechte Deckel über dem Tonarm ist lose und müßte neu verklebt werden (habe es schon versucht, aber es hält nicht ordentlich).Es wäre daher sicher nicht verkehrt, wenn sich der Käufer zumindest etwas damit auskennt und ggf. kleinere Korrekturen/Justierungen selber vornehmen kann. Alleine ein gebrauchtes MMC4-System wird hier schon mit über 100 Euro gehandelt.Da das Gerät sehr schwer und super empfindlich ist, würde ich eine Abholung bevorzugen. So kann sich der Käufer auch vor Ort gleich von dem Zustand des Plattenspielers überzeugen.Sollte dennoch ein Versand gewünscht werden, erfolgt dieser ausschliesslich AUF EIGNES RISIKO und in dem Fall würde ich nur die direkte Überweisung auf mein Konto, oder PayPal an Freunde akzeptieren, um späteren Ärger zu vermeiden. Selbstverständlich würde ich ihn super sicher einpacken und es auch mit Fotos dokumentieren, damit mir hinterher niemand etwas nachsagen kann.Sie können natürlich hier mitbieten um das Gerät zu ersteigern, aber die Bezahlung über eBay würde ich nicht akzeptieren und wieder stornieren, aus den zuvor angegebenen Gründen, die hoffentlich für jeden nachvollziehbar sind. Sollte er beim Transport beschädigt werden, möchte ich nicht der Leidtragende sein, der dann auf dem Schaden sitzen bleibt. Für so ein hochwertiges Gerät lohnt sich vielleicht auch mal ein kleiner Ausflug ins schöne Weserbergland ???? Optisch hat er natürlich ein paar Gebrauchsspuren (siehe original Fotos), ist aber noch absolut Wohnzimmertauglich.Abholung in der Nähe von 31785 Hameln bzw. ca. 50km südlich von Hannover !

Original Bang & Olufsen MMC20CL Cartridge/Stylus perfect working orderChecked 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.

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. This meant that all critical components were designed and constructed as an entity in order to give optimum performance.

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.
