User manual SME MODEL 10 PRECISION TURNTABLE

[. . . ] PRECISION TURNTABLE Instructions 2 Precision Turntable Instructions This is not an ordinary turntable. These instructions cover unpacking, adjustment and installation procedures and you owe it to yourself to read them carefully before proceeding further. 3 1. Introduction The SME Model 10 Precision Turntable is built to exacting engineering standards providing reliability and freedom from critical adjustments. Build integrity, sophisticated electronics and vibration free moving parts allow the full capabilities of any sound system to be fully explored. 4 2.

Specification (turntable) Motor commutation and speed selection are supervised by an 8-bit micro-controller and regenerative braking reduces run-on to a minimum. The special SME motor sets new standards of speed stability and quiet running. [. . . ] In standard operation the mounting surface of the cartridge, underside of the headshell and the centreline of the tone-arm should all be approximately parallel with the surface of the record. The alignment protractor has been printed to act also as a height guide in conjunction with the lines on the side of the tone-arm. Measure the distance from the surface of the record to the upper of the two lines at the front of the tone-arm using the left-hand scale. Reposition the protractor about 6mm (1/4") from the edge of the record. Using the right hand scale repeat the measurement and compare it with the first one. Adjust the VTA screw until similar reading are obtained indicating that the arm is level with the surface of the record. Other dispositions can of course be accommodated and if the readings are noted can be quickly implemented for special needs. With the record still on the turntable, place the alignment protractor onto the record spindle. Move the arm base as far forward as it will go on the turntable sub-chassis. Check that the anti-skate control is at zero and the VTF is set for suit the cartridge in use. Move the arm out of the armrest and place it so that the cartridge stylus enters the indent formed at the intersection of the cross-lines, taking utmost care not to touch or knock the tone-arm once it is engaged. Carefully move the arm base backwards a little at a time until, when directly viewed from above, the outline of the tone-arm coincides with the arm profile lines printed on the protractor. Most cartridges have a stylus - fixing-hole centre distance of 9, 5mm (3/8"). Correctly adjusted with these, the outlines of the tone-arm and protractor will coincide when viewed directly above the centre-line of the tone-arm. With others, according to the position of the stylus, it will be necessary to view slightly to the left or right of the centre line; the only requirement for correct HTA being that the outlines appear to coincide along their length. Replace the arm in the armrest, without disturbing settings, and remove the protractor. 2. 3. 14 20. Keeping the tone-arm in the armrest and avoiding any pressure that might disturb the HTA setting, swing both tone-arm and armrest radially until the left-hand front edge of the headshell is at a radius of 205mm (8 1/16") from the centre of the record spindle. The measurement is not critical within+/- 3mm (1/8") but the accuracy of the anti-skate control will be affected is this is exceeded. 21. The two M4 x 18 socket cap screws securing the tone-arm base to the sub-chassis can now be tightened, followed by the base clamp bolts at the rear. At this point the VTA screw may be removed until it is required again. 22. The dial is calibrated and should be set to correspond with the VTF in use. Rotate the dial until the chosen setting coincides with the index point. [. . . ] Do not alter the factory adjustment unless there is real evidence of need. Spindle lubrication is also recommended after 1000 hours use or two years. With the turntable inverted as for bearing adjustment take out the small screw near the centre of the bearing cap and insert just one drop of oil, from the syringe of lubricating oil. For cleaning the platter should be removed from the turntable whilst its surface is sponged with a soft cloth using warm water and washing-up liquid, followed by warm water only and then a dry towel.
