3. MOUNTING THE TONEARM

 If you have a blank (without armhole) mounting board: NOTE: DO NOT peel off the

protective paper from acrylic boards until after the armhole has been drilled. The

paper will help protect the high-gloss surface beneath the paper.

 Put the arm board back in its original position and fasten it with three screws on

the right-hand side. You need only give the screws a few turns by hand—just

enough to keep the board from sliding around.

 Using the arm manufacturer’s template and per their instructions, mark the

location of the tonearm hole.

 Remove the board from the MK-4 so as not to get any debris on the chassis, and

drill the hole or holes using commonly accepted safety practices including eye

protection and gloves.

 If you have a pre-cut arm board: Confirm that it is the correct board for the arm you

are mounting. Fasten the tonearm to the board according to its manufacturer’s

directions. Do not attach the arm’s cable for now.

 Place the board, with arm attached, in place on the Mk-3. Do not fasten it with the

six arm-board screws yet. Look at the position of the chassis with respect to the

base. If the right corner with the arm in place has dropped more than 1/16” from its

position without the arm in place, you may want to raise the corner for cosmetic

reasons. To raise that corner, remove the board with arm attached and put it down

carefully so as not to damage the part of the arm that extends below the arm board.

 With one hand, lift the chassis off the rear right-hand spring, using the armhole in the

chassis. With the other hand, rotate the spring counterclockwise. One revolution of

the spring raises or lowers it 1/16”. Replace the arm board. This adjustment is only

for cosmetics, so you need not spend an inordinate amount of time on it.

 Fasten the arm board to the chassis with the six screws. Make sure that there is a

washer under each screw head. Tighten each screw well. Attach the tonearm cable

according to its maker’s directions.

 In most cases, the factory spring height setting will not have to be altered. The

chassis normally floats 1/8” to 3/16” below the top rim of the base. If it is within

these limits, no further spring adjustment needs to be made. If you do need to make

further adjustments, all but the left, rear spring can be reached from beneath while

the turntable is still across the two chairs. To reach the left, rear spring, you will

have to lift the chassis. Do remember to take off the belt from around the motor

pulley BEFORE lifting the chassis.

 As a final check make sure that the chassis is freely floating in both the horizontal

and vertical planes. See that it is not touching any of the sides of the base and that

it is not touching the motor housing beneath the left, rear corner.
