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 No cartridge will ever reach this ideal unless the Laws of Physics can be repealed.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.

Fully serviced Bang & Olufsen Beogram 8500 with MMC4 type 5971. One of the last ever turntables produced by Bang and Olufsen Fully serviced with new belts sourced from Beoparts to match same tension as the original specification. Replaced platter belt BS003 Replaced carriage servo belt ref BS023 Regreased carriage servo mechanism. Fully cleaned internally. Cosmetically it is in excellent condition there is barely a mark on it. Barely a mark on it and the matt grey panel looks excellent. The smoke grey translucent dust cover has some minor marks on but these can be polished out. Timeless design by Jacob Jensen. The sound from this turntable is amazing. This was one of the last turntables produced by Bang and Olufsen. The turntable automatically detects the size ofthe record and starts at the correct speed with the 33 or 45 rpm speed lighting up on the tangential arm. The speed can be changed for 12” singles. This turntable is complemented by the Beocenter 8500 not included but will available as a separate listing soon. Please note that within mainland UK I would prefer to arrange delivery myself. The postage costs listed are for someone to drop the item off / meet you somewhere to collect the unit and not for a courier. The postage will help cover fuel costs and can be reviewed with the buyer depending on their location. I am happy to travel 1 or 2 hours to drop it off at a time and date convenient to me which may not be immediately after the sale. I will consider dropping it off at locations further away than 2 hours but may ask the buyer to meet me halfway that way I can cover most of mainland UK. I do travel to the midlands and the south approximately every 2 to 4 weeks. If you are expecting the item within a couple of days of buying then please contact me in advance of purchase to make suitable arrangements. If you are serious about buying the item I am sure we can agree something. Here’s some additional additional information from the Beoworld website… BeoGram 8500 Record Deck Manufactured: 1990 - 1993 Designer: Jacob Jensen Colours: Grey To complement Beocenter 8500, a dedicated record player - Beogram 8500 - was designed specifically for this particular hi-fi centre. The technical aspects of Beogram 8500 were identical to Beogram 9500; it was only the finish that was different which was coloured soft grey to complement the rest of the system. __________________________________ BeoGram 8500 Record Deck Product Specifications Types: 5971 (1990 - Oct 1993) J 5973 (1990 - Dec 1990) Speeds: 33 - 45 rpm Speed deviation: < +/- 0.2 % Wow and flutter, DIN: < +/- 0.06 % Rumble DIN weighted: > 80 dB Rumble DIN unweighted: > 55 dB Power supply: 5971: 220 V 5973: 100 V Power consumption: < 10 W Dimensions W x H x D: 42 x 7.5 x 32.5cm Weight 5.3 kg Link compatibility: Data Link
