    LINN SONDEK LP12

    SET-UP MANUAL

    IT IS EXTREMELY IMPORTANT THAT YOU READ THIS ENTIRE MANUAL BEFORE ATTEHPTING TO

    SET UP YOUR LINN SONDEK LP12. FAILURE TO DO SO'WILL, AT BEST, RESULT IN

    SUBSTANDARD PERFORMANCE, AND MAY, IN EXTREME CASES, RESULT IN PERMANENT DAMAGE

    το ΤΗΕ TURNTABLE .

    We realize that the policy of most hi-fi enthusiasts is, "If all else fails,

    read the instructions". However, the set-up procedure used on the Linn Sondek,

    while not terribly difficult, is significantly different from that used on

    other turntables. It is virtually impossible to set the table up correctly

    without following the steps in this manual.

    These ίπ5(τυειίοπ;.τεξ€τ specifically to the set up of the Linn Sondek LP12

    when it is being fitted with a Linn tonearm and cartridge. Appropriate

    notations will be made for variations in procedure for other arms and

    cartridges (see "Selecting a Tonearm and Cartridge").

    WHAT VE MEAN BY TIGHT

    Since we are dealing with a transducer that has to recover information

    considerably smaller than a millionth of an inch from a phonograph record, it

    is important that all the fasteners (nuts and screws) in the turntable be very

    tight. k‘henever the instructions call for you to tighten a fastener, we do

    mean TIGHT, probably tighter than you ever would have imagined. However SANITY

    MUST PREVAIL in tightening these fasteners. There is no advantage to

    tightening them past the point where the associated material will deform, since

    you are then simply stretching or crushing the materials involved and

    destroying the structure. A good rule of thumb is simply to bring the nut or

    screw up to where it seems very tight and then turn it about 1/4 turn more (in

    the case of armboard screws, which are put into wood, 1/8 turn will do).

    TOOLS NEEDED

    5/16" or Emm Hollow Shaft Nut Driver

    #2 Philips or Posidrive Screwdriver. (The cross slot screws on the 1.912 are

    pusidrive, but Philips will work.)

    #1 Philips or Posidrive Screwdriver.

    Medium (about 5/32" wide) Flat Blade Screwdriver wi th large handle (This is for

    cartridge mounting--a jeweler's screwdriver will not do!)

    Medium Needle Nose Pliers.

    2mm Hex Key (allen key)

    2.5mm Hex Key (allen key)

    Hex Keys supplied with tonearm.

    Turntable Set-Up Jig or substitute. (It will be necessary to have the

    turntable up where you can both reach and see the u nderside of the table. Linn

    dealers have a special set up jig for this pur pose. If you are doing this

    without a set up jig, it will be necessary to suspend the table between two

    objects. Make sure they are steady enough a nd stand firmly enough that they

    will not tip or slide and allow the turntable to fall.)

    STEP BY STEP TURNTABLE SET—UP

    ***>…****************************** CAUTION! ***-********************* **********

    MAKE SURE THAT THE TURNTABLE IS UNPLUGGED FROM THE A/C OUTLET BEFORE REMOVING

    THE BOTTOM COVER! HIGH VOLTAGES ARE AVAILABLE ON THE CIRCUIT BOARD! FAILURE

    ТО OBSERVE THISHPRECAUTION CAN RESULT IN SERIOUS ELEC TRIC SHOCK!

    Please note that, on turntables equipped with t he Valhalla circuit board, the

    board is "live" at all times. The on/off switch does not turn_ the A/C on and

    off, it simply sends 2a control pulse to the board which results in the motor

    being turned on or off.

    PREPARATION

    l) Unpack the turntable. The dustcover will be packed in the top. Below this

    will be the top paERing block, which should contain the following: I ermboard,

    2 dustcover hinges, 2 screws, l inner platter/spindle assembly, 1 vial of

    bearing oil. (See packing diagram)

    2) Place the turntable in the set up jig (see "TOOLS NEEDED " above), and lock

    it in place.

    Steps 3 through 9 will involve checking to see that none of the

    fasteners on the table have loosened in transit from the factory.

    3) MAKE SURE THE А/С POWER IS DISCONNEC TED! Remove the bottom cover by

    removing the two front feet, and loosening the back two feet until they release

    the cover. lf you are working on a previously set up table, you will have to

    remove the screw that is located halfway between the two front feet and the

    corresponding screw between the two back feet. (SEE "PACKING CAUTI ON" NOTE).

    Δ) Use the 5/16" or В mm nut driver to remove the nuts ho lding the ground wire

    and the P—Clip to the main assembly bolts. (See "Tur ntable Layout" diagram).

    5) Check to see that the nuts found above these n uts on the main assembly

    bolts are tight, and tighten them if they are not . The main assembly bolts

    pass through the wood mounting blocks of the base, and can work loose due to

    the expansion and contraction of the wood.

    ь) Looking dom at the stainless steel top plate from a bove, locate the two

    small posidrive wood screws that fasten the top plate to the blocks in the

  • FA.-CE 6 LINN SONDEK LPlZ SET—UP MANUAL

    wood base. They can be found next to the main assembly bolts located πι the

    center front and center rear of the top plate. Hake sure tha t these two small

    wood screws are tight.

    7) Check the mounting position of the motor. The motor mounting bolts m ount

    in elongated slots. (Refer to the "Motor Haunting Diagram".) On turntables

    with the large БОН: pulley (27/32" or 21 mm diameter), the motor sits in the

    middle position. This is most easily accomplished by havin g one motor mounting

    bolt at the outside of the slot, and the other a t the inside of the slot. On

    decks with the smaller 60 Hz pulley (ll/16" or 17 mm pulley diamete r), the

    motor should be in the outermost position, which is accomplished by having both

    motor mounting screws at the outside of the slot. ON NEW TABLES, THIS POSITION

    SHOULD ΒΕ εοκκΞ(:τιΥ SET FROM THE FACTORY.

    Please note that all new turntables; ile., those that come

    factory equipped with a Valhalla circuit board, use th e larger 50

    Hz pulley and thus should have one motor mountin g ball: at the

    extreme outside end of its slot and the other bolt a t the extreme

    inside position.

    8) Check that the motor mounting screws are tight. Onc e again, there is no

    advantage to over tightening these screws! You will simply crush the motor

    mounting domes (refer to the "Motor Mounting Diagram").

    9) Check that the bolts that mount the ma in turntable bearing to the sub—

    thassis are tight. These are accessible from the top, throngh the hole in the

    Center of the stainless steel top plate, by shi fting the sub chassis from one

    side to the other. Current Linn Sondeks use 2.5 mm metric hex key bolts, older

    units may use 2 mm or 2.35m hex key bolts, philips scre ws, or slotted screws.

    ARM MOUNTING

    10) Unbox the tonearm and cartridge.

    ll) Mount the arm base on the tonearm board. In the case of the Linn arms,

    this is affixed with three metric socket head cap screws from the bottom.

    These should be tightened until the serrated lo ck washers just begin to sink

    into the armboard. On arms using other mountin gs, make sure the mounting

    screws or nuts are very tight. On arms using a single large mounting nut, this

    does mean using a wrench, not your fingers.

    12) On the Ittok, or other arms using independe nt armrests. mount the armrest

    on the armboard. There is a pop—out plug in the arm rest hole of pre—cut Linn

    armboards, which you must remove. Orient the a rmrest so that th
