Revised Jan 1998 IN THE BEGINNING ... This is where it all began back in 1973 - the Sondek LP12, which revolutionised people’s perception of what pro- duces ‘good’ hi-fi. At Linn we have demonstrated that turntables are the most important component in a record playing hi-fi system.
It is extremely important that you read this entire section before attempting to set up a Linn Sondek LP12 Turntable. Failure to do so may well result in substandard performance, and could result in perma- nent damage to the turntable.
8mm or 5/16 Hollow Shaft Nut Driver No. 1 Pozidrive Screwdriver No. 2 Pozidrive Screwdriver All cross slot screws on the LP12 are Pozidrive. While a Phillips screwdriver will work, the correct Pozidrive screw- driver is preferred. Medium Size (about 5 mm wide) Flat Blade Screwdriver...
Revised Jan 1998 LP12 SET-UP JIG We recommend that you always use a set-up jig when setting up an LP12. This will facilitate ease of adjustment, prevent damage to your turntable and ensure proper suspension adjustment. Before using the jig make sure that the mounting plates have been covered with a protective strip.
(base) is level. This is done by adjusting the feet of the set-up jig. Please note that if you are using a Linn set-up jig, you may lay the jig on its back at various times during set-up to provide easier access to the underside of the turntable (steps 3 to 6 for example).
Procedures may vary slightly if other tonearms are used. 11. Mount the Tonearm Base on the Armboard In the case of the Linn arms, the arm base is fastened from the bottom of the arm board with three 4mm socket head bolts with lock washers.Read section on Kinky arm...

See Seperate proccedure for complete details. 16. Charge Turntable Bearing with Oil Discharge the entire charge of oil provided into the bear- ing well - i.e. two small 1 ml phials of Linn oil. Wrap a tissue around the bearing housing to absorb any overflow.

If the cartridge body is not strong enough to allow it to be mounted tightly, it cannot perform at its best. All Linn cartridges, except the K5, are metal bodies and can be tightened properly. To avoid damaging critical arm bearings never, under any...
(and hence the arm bearings) is deformed. If mounting a Linn Ittok LVIII arm, at this time you should readjust the height of the arm rest and tighten the knurled height locking screw as tightly as possible.

If you are setting up an older LP12 that does not have this allen screw attaching the chassis earth, it is recom- mended that you drill a small hole (3mm) on the side of the sub-chassis and relocate the earth wires to this point.
Speedchecker. A drift of one line per second indicates a speed error of only 0.3%. With the use of the Linn Speedchecker, it is quite easy to adjust the speed to within 0.01%. Finally check with the outer platter fitted upside down that belt does not foul belt guide and runs on crown of pulley.

(this is not a motor fault). Remove end cap from the motor and check ball bearing is properly greased. Use Linn black grease only. Refit the assembly to the bottom of the motor. After replacing the cap, push down on the motor pulley from above. The pulley should go down, then spring back to its original position when released.
Carry out the "Tune Dem" to estabish correct setup before and after carring out any modifications or upgrades to ensure that you are getting the best from the LP12. Tips: When fitting Linn Tone-arms split the arm cable...

50 Hz or 67.5 Hz square wave for 33 rpm and 45 rpm respectively. As the LP12 motor runs at its quietest when driven with a clean sinusoidal waveform, a precision filter is employed in the Lingo to remove harmonics from the square wave leaving only a pure wave form.

Estimated Time for Completion of task ~ 30 minutes WARNING: Disconnect the Mains Supply from the Turntable Remove the base from the LP12, remove all the wires from the Valhalla board terminal blocks and remove the old switch assembly. Take the Valhalla board squeezing the stand-off clips with a pair of long-nose pliers.
When updating older LP12s remember to change all the suspension grommets and related parts to those listed below. These parts are also supplied in the LP12 Spares Kit (part no. SK-LP12) or in the CIRKUS bearing upgrade. Components...
In 1991 a Factory fitted new small thrust cap was intro- duced. This replaces the previous motor thrust bearing arrangement and is suitable for all LP12's. As this is glued in place it requires no maintenance, and cannot be re-trofitted to existing motors.
The complete kit of parts, which includes a new inner platter and spindle, is supplied to fit this upgrade. As always with Linn product improvements, all new LP12 turntables since April 93 have incor- porated this upgrade as standard.

Failure to replace both components will result, except in the case of a new, unused LP12 in a rapid deterioration of performance. All required parts are supplied in the CIRKUS Kit (page 38). Oil Change...

Fix the new bearing housing using the screws supplied with the bearing; tighten them as much as possible, avoiding distortion of the chassis, then ft to LP12. 10. Refit wiring strap, motor wires, arm cable, earth wire, flexible pcb switch connector and base board.
ARMBOARD Introduced - 1987 Serial No. (approx.) - 79,160 The latest LP12 armboard is made up of an MDF core, laminated top and underside. This improvement better optimises the rigidity of the arm board. Most LP12s are fitted with the EKOS armboard which accommodates Ekos and Akito tonearms.
The Valhalla will drive almost all LP12 motors, with the possible exception of very early motors (coded MB10). It drives the motor with 85V A/C across the red phase. The blue phase is driven through a phase shift capacitor at approximately 75 V.

As of May '91 all motors for LP12 Valhalla and Lingo are supplied with a new smaller motor end cap glued in place. For previous motors see the following section.

Remember that there is a running-in period for new motors of up to 36 hours continuous running. You can accelerate the noisy run-in period by leaving a Lingo LP12 on at 45 rpm overnight for a few nights to quickly achieve quiet running in the new Lingo position.
Revised Jan 1998 LP12 45 RPM ADAPTOR A 45 rpm adaptor is available for the LP12 turntable and is supplied as standard with the Basik power supply. The adaptor consists of a slip-on ring which fits over the existing pulley, and a new belt. The old belt should be used with the adaptor, the new belt being intended for use at 33 rpm.
Fitted with additional stud which improves the coupling of the top plate to the Plinth and secures the motor corner. Mar. 1992 88950 LP12 Mechanics Only LP12 sold as a mechanical assembly only.
