Dem Alter entsprechend sehr schön erhaltener Bang & Olufsen Beogram 7000 Plattenspieler mit MMC2 Tonabnehmer. Zum Defekt: Der Tonarm bewegt sich nicht , höchstwahrscheinlich , weil ein dünnes Drahtseil, das meiner Meinung nach den Tonarm bewegen sollte, augenscheinlich lose im Gerät liegt. Bei der Nadel bin ich mir nicht ganz sicher, sie produziert zwar einen sehr schönen Klang, aber nur, wenn man den Tonarm kurz antippt - keine Ahnung, ob die Nadel selber was hat oder es damit zu tun hat, dass sich der Tonarm nicht so bewegt, wie er sollte. Alles andere funktioniert : Start, Stop, Lift, Licht, Geschwindigkeiten, Verbindung mit einer B&O Anlage. Youtube Video hier : youtube.com/watch?v=URNM2dchGBs Link markieren, kopieren und in die Adressleiste des Browsers einfügen. Im Video sieht man , was er kann und was nicht. Er gehört halt repariert, dürfte aber nicht allzuschwer sein, denke ich. Natürlich ohne jegliche Garantie oder Gewährleistung - für den Versand wird er ordentlichst verpackt und der Tonarm unterlegt. Am 21.10.23 hat der Verkäufer die folgenden Angaben hinzugefügt: PS : ebay gibt automatisch vor : Rücknahme akzeptiert - das trifft nicht zu.  Keine Rücknahme, Garantie oder Gewährleistung, Verkauf als teildefekt laut Beschreibung und Video - der Tonarm bewegt sich nicht, der Zustand der Nadel ist fraglich - siehe Video und Beschreibung. Bitte bieten sie nur, wenn sie damit einverstanden sind. Ich habe keine Lust , das Gerät nach 14 Tagen ausgeschlachtet zurückzunehmen -  das ist mir leider auf ebay schon passiert, wenn auch nur  mit einem Kaffeevollautomaten.

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.
