This was in my Dad’s stuff. He always took great care of his record collection and audio equipment. Comes with the original box and tools. Please let me know if you have questions or need more pictures. Thanks, B.

Does not include cartridge Has a hairline crack in back plastic dust cover bracket (can only be seen if you look closely) ... the dust cover has one of the plastic hinge pieces broken. I believe the issue with this unit is the RCA output cables they are not making a great connection with the amp. The platter turns and everything else seems to work it is just crackily when you jiggle the rca plugs on the output wires. On the right side the veneer strip needs to be glued back on, it is included... this unit is being sold as is. Includes original box!!

The aluminum strip that slides in on the front of the Beogram 3400, with the model name and the name of the company. Near perfect condition, minimal signs of wear or age.

Selling as is. I have to say for parts because I have no way to test it. I plugged it in and it powers on and you can select record size. Has what I assume is cartridge under arm, see pics. It was an estate find, but everything in this house was perfect so Im assuming this is too, but I cant say for sure. No chips or cracks in the cover. Little dusty but its nice.

First the good things: Tested the MMC 20EN cartridge and it tracks nicely and sounds good. Returns at the end of the record properly. Some paperwork included. Plinth and belt are all good and the dust cover as well but its not attached. Second, the bad things: Dust cover is not attached. There is a small bag of pieces that I think go with the dust cover attachment. Not sure but I think they are. And last but not least, the table will only turn if you press the turn and stop button at the same time. If you do that its fine and works properly. Be advised. Will be packed properly with transit screws tightened. Sold as-is. No returns. Almost forgot... the Rolling Stones Sticky Fingers 33 LP is included. Thanks for bidding!

Original Bang & Olufsen MMC20CL Cartridge/Stylus perfect working order Uk stock ready for dispatch NOW Checked 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.
