FEEDBACK FROM A PREVIOUS BUYER:Dear David My Mum is now playing her records again. After ten years! She is absolutely delighted. You dont often get the chance to surprise and delight an 80 year old lady. Thanks so much for your help. BeoCenter 4600 Manufactured: 1977 - 1980 Designer: Jacob Jensen Colours: Rosewood, TeakBeocenter 4600 was a multi-way combination unit incorporating a 2 x 25 watts RMS AM/FM receiver, an easy to use hi-fi cassette deck and an automatic record player. The lightweight arm had built-in bias compensation and carried Bang & Olufsens MMC 20S pickup cartridge with spherical diamond stylus.The AM radio covered long and medium wavebands. Outstanding reception quality and high selectivity was secured by an Automatic Gain Control circuit, active noise suppression and hybrid filters.The FM tuner was highly sensitive. Four stations could be pre-set for subsequent instant recall. The hi-fi cassette deck had all the features and qualities normally expected only in a separate deck:* 3-digit counter with memory function* electronic tape stop at end of play* Dolby B Noise Reduction* chrome or normal tapes could be usedThe super Permalloy tape head was hard-wearing and had a long, useful lifetime. The record player too was automated: all functions were controlled by a single button. The anti-skating device worked automatically too. Bang & Olufsens MMC20S pickup cartridge with a spherical diamond was an integral part of this unit. Two Beovox S40 speakers complete this system if this was your choice.

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. 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.

BANG & OLUFSEN MMC 20S STYLUS NEEDLE B&O FOR BEOCENTRE & BEOGRAM TURNTABLES LIGHTLY USED CONDITION AND PLAYS SUPERBLY. MMC20SManufactured: 1979 - 1985Designer: Jacob JensenColours: Black MMC cartridges were available with standard ½ mounting brackets, or with easy plug-in, lightweight connectors. These enabled you to mount MMC cartridges onto non-Bang & Olufsen arms. The cartridges plugged directly into Beogram pickup arms without additional mounting gear MMC 20 S was a stereo cartridge with a spherical framed diamond. In 1958, Bang & Olufsen introduced the first stereo pickup cartridge ever made in Europe. This was called the SP1. Since then, many design innovations and the creative use of new materials have kept B&Os cartridges at the forefront of audio technology. By 1979 - 80, Bang & Olufsens cartridges were represented by the MMC 20 series. 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 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. The MMC20 series therefore represented the closest that modern technology at that time, could possibly afford.

The result is a system which not only reduces damage to the groove walls dramatically, but also provides exceptional performance at all frequencies. Bang & Olufsen cartridges have always been highly acclaimed for their low ETM values. The ETM of the standard MMC 20 range, only 0,5mg. MMC cartridges were manufactured by Bang & Olufsen as totally integrated units. This means that the elements were matched, balanced and sealed at the factory. Using a computer-supported testing programme,, each sealed unit was meticulously tested and its performance information automatically registered and packed with each cartridge. The information given included output voltage, relative voltage output (channel balance), channel separation and frequency response. Individually-calibrated frequency response curves were also supplied with the higher-specified MMC 20CL cartridges.

bang olufsen beogram 1100 turntable Type 5705 with stylus MMC20s+ BEOMASTER 1900. Both are Untested apart from switching on . The turntable turns and seems to be working fine. It is in good cosmetic condition apart from the cover not sitting correctly. It will need looking at. The beomaster 1900 lights up then turns off in a few seconds. Im not technically minded so I refrain from attempting to fix it. So for that reason the beomaster and beogram is faulty and both sold as seen for spares or repair. Im willing to post but prefer the system to be picked up in person if possible Thank you for your interestOn 20-Jun-23 at 21:52:05 BST, seller added the following information: Please note, bought as faulty/ not working, no returns.
