3. MAINTENANCE

3-1. Changing the capstan

The SR-1050s power source frequency has been
properly adjusted for the area. If the turntable is
brought to the country or area where electrical cycles
change from 50 to 60 Hz or vice versa, an adjustment
in the turntable speed is necessary as follows.

1. Remove the turntable (platter) and belt.

2. Loosen the setscrew of the capstan and pull
the capstan up.

3. Attach a proper capstan (the thicker one is for
50 Hz).

4. Adjust the height of the capstan so that the belt
moves smoothly while changing the turntable
speed from 33'l3 to 45 rpm or vice versa, then
tighten the setscrew of the capstan securely.
