Biete: Stereoanlage B & O - Beocenter 2800. Eine Rarität und ein Stück Zeitgeschichte. Plattenspieler, integrierter Verstärker, Radio (Tuner). Mit original Tonabnehmer in gutem Zustand. Im Grunde funktioniert alles, aber die Regler (Poddis/Potentiometer) kratzen - z. B. Sendersuche: Ton - kein Ton - wieder Ton - hin und her - Ton. An Reglerstellen wo man den Ton hat ist er sehr gut. Plattenspieler soweit ich es prüfen konnte o.k.- Automatik funktioniert, Gleichlauf unauffällig. Gebrauchsspuren sichtbar vorhanden z. B. an der Abdeckung. Aber noch absolut wohnzimmertauglich. Abholung in 93189 - oder Versand 10,49 €. Auf Grund des Alters und des kratzenden Reglers als Bastlerartikel zu verkaufen. Bei Fragen schreiben. Privatverkauf, keine Garantie, keine Rücknahme, Bilder sind Teil der Beschreibung.

Original Bang & Olufsen MMC20E Cartridge/StylusUk stock ready for dispatch NOW Checked on a spectrum analyser, delicate, accurate and precise.Tracking perfectly.Sounds great.Stock images appearance will vary slightly.BANG & OLUFSEN MMC20E CART & STYLUS BEOGRAM 6000 4000 8000 BEOCENTER 7000 7002 3600 4600Inspected, tested - see images MMC means Moving Micro-Cross Titanium-bonded naked elliptical diamond, to reduce record wear and maintain optimum surface contact Effective Tip Mass of mg 0,4 this is what preserves your vinyl! MMC20EManufactured: 1979 - 1985Designer: Jacob JensenColours: BlackPrior to the release of MMC1 - 5 cartridges, Bang & Olufsen had the following MMC range of combined styli and cartridges: 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 MMC 20 E was fitted with a framed elliptical diamond which has a high polish MMC 20EN had a naked elliptical diamond, mounted on a tiny tapered cantilever MMC 20 CL utilised a Contact Line naked diamond mounted on a single crystal sapphire cantilever. This shape ensures maximum groove contact. This was the most highly-specified cartridge in the MMC 20 range 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. 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. Bang & Olufsen cartridges have always been highly acclaimed for their low ETM values. The ETM of the MMC 20CL is a mere 0,3mg and in 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 Beocenter 2800 Record Player Radio Untested. This music centre is untested and comes without speakers. Here is what I know. 1.The turntable spins and changes speed and I am told it works and i dont see why it wouldnt but would need a stylus to test. 2.I have plugged in but no lights come up on the radio functions so Im not sure if it works. 3.The front buttons are quite sticky and dont pop straight out. 4.Lid is good - no cracks 5.It comes with original polystyrene padding for turntable and tone arm plus original manual. 6.Will be securely packaged and insured for delivery. Hopefully it works or is an easy fix ,otherwise lots of good spares.

Bang & Olufsen Beocenter 2800 hi-fi system - with MMC 20 S stylus + 4 B&O speakers A true classic of a hi-fi system!! I bought this second hand 8 years ago and it had just had a new turntable belt - it has not seen a huge amount of use, perhaps an hour or two each month. I play old vinyl and newer heavy vinyl and both play ok but the right hand channel sometimes drops out - I’m not sure how much is down to the quality of some of my vinyl or down to the stylus. This does not happen when playing from my phone via the tape input so that tells me the amplifier is ok. 50 watt amplifier (2 x 25). Dual output so 4 speakers can be connected (4 x 12.5) and individually selected as each pair or both pairs. Volume, bass, treble, balance all working. The FM tuner works - the rear antenna socket is loose but still functional. Phone / MP3 music can be connected via the “tape” - I play from my iPhone and it works great, see pics. I will include the cable for this. 2 x S60 watt speakers - fully functional. 2 x S75 watt speakers - fully functional. Speakers 590mm (H) x 320mm (W) x 230mm (D) - either vertical or horizontal mount. Speaker S60 or S75 badge rotates to suit how speaker is orientated. All speaker cables included. Overall in good presentable condition. No signs of any damage. This is a 40-50 year old iconic hi-fi brand, I am only selling as we plan to move and I need a system with smaller speakers. Collection only due to weight. Located in Surrey 10 minutes from J7 or J8 of M25. PLEASE NOTE ….. PAYMENT ON COLLECTION, DO NOT MAKE PAYMENT PRIOR - I WANT YOU TO BE HAPPY WITH THE ITEM BEFORE YOU TAKE IT AWAY. CASH ON COLLECTION.
