The transition point between these two conditions is important for a clean low frequency response and is established by the compliance of the cartridge and the total effective mass of the arm and cartridge body. At audio frequencies however the increased resisting force causes the armature to move relative to the stator and a signal is produced. At subsonic frequencies the armature and stator move as one allowing the slow movements needed to negotiate the record surface without generating a signal. It is this resisting force which makes the operation of a cartridge possible.
The effective mass of an arm and cartridge resists motion least at low frequencies but increasingly as frequency rises. The first property is mass which opposes any change in motion. In common with any mechanical device the behaviour of a pick-up arm is governed by three properties of matter that also define the laws of motion. The following notes will help a better understanding of the problems and how they were resolved in this radically new design. The result is a subtle loss of clarity, dynamic range and transient attack that can make the sound from even the best system tiring to listen to. Unless the pick-up arm holds the latter against even the minutest movement at audio frequencies the signal will be modified in some way. Reproduction can only be true therefore when all movement representing groove modulation is made by the armature to which the stylus cantilever is attached and none by the stator represented by the cartridge body. All cartridges employ relative motion between armature and stator portions of a generating system to produce the signal output. Good luck.The functioning of a pick-up arm appears simple but is in fact very complex. If you do not agree or cannot comply with the above terms, please do not bid. If you place a bid and are away for a few days after auction end, please notify us in advance, otherwise the item will be re-listed or offered to the next highest bidder. Auction items are not included in return policy and are sold as is. Buyer to contact us before returning goods. This applies to â� BUY IT NOWâ� items only and buyer to pay all postage costs. If we have heard nothing from you within 3 days of auction end, we will email you a reminder stating that we will be re-listing or offering the item to the second highest bidder on the following day.Returns accepted within 7 days as long as in condition sold and in same condition as received. Payment expected within 4 days at the latest from auction end. We expect contact within 3 working days (ebay rules, not ours) or otherwise We reserve the right to relist the item or offer to the next highest bidder. We accept cash on collection, bank transfers and Paypal. Winning bidders paying by Paypal will have to have signed for delivery. The winning bidder will be sent an invoice with the exact price shortly after auction end. We can send this item anywhere in the World at the winning bidders expense.Starting at only £0.99, someone may well get a bargain.I can never know exactly what the costs will be to post this items abroad as I do not know what country the winning bidder may be from, so we have estimated the cost to most European countries at around 18 GBP. Not as good as the famous Shure V15/III, but a close match and a wonderful rich sounding cartridge.Will be carefully packaged for safe delivery.Lots of high quality pictures at the foot of the text. If it bothers the winner I think SME may have a gasket or whatever it needs, but its never bothered me as I gently lower the arm anyway.I decided to leave a Shure M95ED cartridge in situ. My one is the same and this often happens to these early tonearms. I can change this to phono plugs for the lucky winner if desired.The arm lowering device appears to have lost a little oil. This arm was used with a Quad 33 pre amplifier, so still has the 5 pin din plug fitted to the arm lead. Not much difference between these and the SME 3012 IMHO, and this tonearm.Supplied with unused protractor as well as an SME booklet and new rubber bushes. I use the same version as this myself on my own Garrard 301, the only difference being mine is the SME 12 inch version. It even has the extra rider weight that would be required for such a heavy cartridge.
Here we have a very early SME 3009 series 2 tonearm that is the highly desireable split weight version that was often used with the famous Ortofon SPU cartridges.
