Then finish off the job with a chisel.Īfter fitting a new arm you can find printable instructions for setting up your Linn at Linn Sondek LP12 turntable instructionsĪlternatively you can order all Origin Live arms with “Linn geometry” – see arm options in ordering process.
#SME TONEARM SPACER SERIES#
Probably the quickest way to achieve this is to drill a series of 4mm holes as close as possible to one another in the shape of the cut out you need. This is easy to rectify by removing a small semi-circle of the brace. On newer Linns the wooden corner brace has been increased in size which creates a slight foul with Standard size Origin Live and Rega arms. Alternatively you can get a blank arm-board from Linn and get it drilled. We can supply you with a Pre-drilled armboard for the Origin Live and Rega arms – this board is identical to the Linn armboard but is missing the Linn Logo. If you have a Linn LP12 turntable with a Linn arm then the arm hole on your current armboard will be in the wrong position (Linn arms mount at a distance of 211mm from the platter spindle). Alignment makes an audible difference but in the scale of other parameters it’s really not a lot. A cartridge is only aligned at 2 points on the record – For the remainder of positions on the record it’s out of alignment – We say this to save fretting over the last 0.5mm accuracy and give a bit of perspective. Note: Cartridge alignment is at best only ever a compormise. The overhang from pivot point at rear end is 50mm to the end of the counterweight stub. The length of the arm from its mounting hole center to the cartridge end of the arm is 309mm.
#SME TONEARM SPACER PLUS#
The arm protrusion from pivot point to the rear is 50mm to the end of the counterweight stub.įor Encounter arms and above – If the top of the armboard is around 24mm below the top of the platter then the arm will be at its lowest position for tracking a normal cartridge (17mm body height) and can be raised by a further 14mmįor 12 inch arms only – Centre of 23mm – 25mm diameter hole for arm mount to centre of platter spindle is 295.6mm plus or minus 1mm. The effective length of the arm from its mounting hole center to the cartridge end of the arm is 240mm. The arms can rotate to be clamped at any angle. The distance from the centre of arm hole to centre of platter spindle needs to be 222mm plus or minus 1mm. * Arms below Encounter use VTA adjustment on the arm mounting thread itself so armboards need to be around 20mm or less to allow adjustment. * You need not worry about VTA for Encounter arms and above as they have integral VTA adjustment. The armboard can be any thickness up to 25mm for this to work. For best performance you do not want a tight fit and so all you need do is put a rubber band or wrap a shallow strip of card around the arm base – anything that will act as a spacer – it does not need to be a machined sleeve.Īrmboard thickness: Once the arm is inserted through this hole, you secure it with a large nut under the armboard which clamps it in position. If the hole in your armboard is say 1mm or more oversize then all you need to do is centralize the arm in the hole. The tone arms require a single hole in the armboard or plinth – from 23mm to 25mm in diameter (23mm is ideal for accurate fit). Hole Diameter: You can fit Origin Live arms to any deck but sometimes your armboard may need modification or changing to a new one – (contact a dealer or the turntable manufacturer for the second option). Other solutions include simply cutting a cover disc from black card or thin plastic.

The solution to tidy up the looks is either to fill the 3 holes with dummy round head M3 Allen bolts or you can order a 1mm thick formica black disc from us to cover the holes > see link Disc to cover 3 Rega mounting holes. The only question some people raise after fitting their Origin Live arm is that 3 mounting holes remain visible if the mount is the 3 point type of Rega mount. Neither does the model number or vintage of a Rega arm make any difference. It makes no difference if the Rega mount you have is the later 3 point mounting or earlier single hole mounting. This easy swap is down to the geometry of Origin Live arms being identical to all Rega arms. No additional holes are needed, no modifications, no extra fittings, no VTA adjusters. All standard length (239mm) Origin Live arms will fit directly into all standard Rega armboard mounts. Rega arms and their modified versions (i.e Michell, NAD etc) are easy to replace with an Origin Live arm. This is the simplest case so we put it first. You can fit Origin Live arms to most decks without too much problem.
