Serial number 81,000 onwardsġ990 Lingo direct coupled power supply for the LP12, offers low noise oscillators, precision filtering, separate drive for both phases and electrical isolation from mains supply.ġ991 Lingo has motor thrust pad small cap factory fitted (glued in position) to reduce noise level. Serial number 79,700 onwards.ġ989 Grommets composition changed to a new harder, denser rubber. Reduces motor noise(performance upgrade). Serial number 79,160 onwards.ġ989 Motor thrust pad, motor thrust pad replaced with stainless steel ball bearing. Increases rigidity of armboard, creating improved platform for tonearm (performance and Aesthetic upgrade). Serial number 70,000 onwards.ġ987 Armboard material changed to MDF core, laminated top and underside. Tightened grinding tolerance(performance upgrade). Bearing liner machined to tighter tolerances, thus creating better speed stability. This was a cosmetic update.ġ987 Bearing housing, improved bearing liner material and thrust pad specification. Serial number 54,100 onwards.ġ986 Lid is changed for translucent type.
LINN EKOS HISTORY UPGRADE
We would recommend that if you have a deck without corner braces or this stud the best initial upgrade would be to consider swapping the deck mechanics for the latest version. This is also a very worthwhile improvement and isn’t retro-fittable.
late ’70s Attached strengthening bar with epoxy glue. Serial number 53,000 onwards.ġ984 Sub-chassis, added strengthening bar, spot welded in place. Serial number 38,800 onwards.ġ984 Plinth, enlarged corner blocks, strengthens and increases rigidity of plinth(this was very worthwhile, it not only improves the sound but also makes the plinth less prone to twisting over time). Isolates the rotation of the turntable motor from variations in the electrical supply(This offered a big performance upgrade and even though they don’t make these any more they are preferable to the Hercules version). Serial number 32,800 onwards.ġ982 Valhalla power supply, electronic speed control with a sophisticated crystal controlled power supply. Improved suspension and stability(performance upgrade). Serial number 27,000 onwards.ġ981 Nirvana kit Improved material specification of many integral mechanical components. This was mainly an Aesthetic improvement. Serial number 23,000 onwards.ġ979 Lid and hinges lid prop removed and hinges changed to spring loaded, self supporting. Serial number 2000 onwards.ġ978 Top-plate added two holes for 6 x 0.5 self tappers into wood block(makes the top plate more rigidly held and improves the performance. Main bearing liner material changed(Performance upgrade). Sub-chassis strengthened by addition of strap, spot welded in place (performance upgrade). Motor control PCB was changed from terminal strip to small circuit board. Serial number 0000 onwards.ġ974 Mains switch changed from two buttons to single switch with mains neon. Mechanics were manufactured by Castle precision Engineering. The Grace arms and Supex cartridges were often used(LINN later became the UK distributor for these). At the time LINN did not make arms and cartridges. Later a version with a plinth was also made available. Early versions are sold as a motor unit only without a plinth. LINN LP12 timelineġ972 The Linn Sondek LP12 is introduced onto the market. Checking arm bearings are functioning correctly is also very important as an arm bearing rebuild costs £300-400. We would also recommend that versions with the spot welded stud on the top plate are much preferred to those without. Some very early plinths are prone to warping which makes setting the suspension more challenging as the top plate no longer sits correctly. Whilst a lot of the upgrades over the years can be retrofitted some cannot and make a significant difference to the performance. Quite a lot of online sellers see current prices and assume their vintage deck is worth what a current model would be. The earliest decks were supplied as motor units only with no plinth.īuying a second hand deck can be a great way of getting an LP12 but caution and care must be taken over the specification and condition before laying out what can be a significant amount of money. complete with plinth and lid with Acrylic support prop. The advert picture below shows a very early example. To get a better idea of the changes that have taken place check out our LINN LP12 timeline.
To bring an original deck up to the current spec would require pretty much every component in the deck to be replaced. Despite the appearance staying very similar to the original product it has undergone numerous upgrades which make a modern deck a very different beast to those units made in the early seventies. The LP12 is an iconic turntable, it is probably one of the longest running audio products in History.
