** In order to replay shellac records at 78 r.p.m. your turntable must be equipped with the 78 r.p.m. pulley

which is available as an optional accessory for most models.

After fitting the 78 r.p.m. pulley please proceed as follows: Remove the platter and using the tool from the

accessory kit fit the belt around the larger diameter step of the pulley. Replace the Platter, start the turntable

at 33 r.p.m. and switch the speed to 45 r.p.m., the platter will then revolve at 78 r.p.m..

Remove the platter and drive belt. Please remember that sweat or sticky fingers will impair the function of the

belt. Use a piece of kitchen paper or a cloth to remove the belt.

Measure the height of the pulley above the plinth in order to ease correct refitting.

Using a small screwdriver loosen the grub screw in the neck of the pulley just enough to remove the pulley

vertically without using force. Refit the pulley in the opposite order. Tighten the grub screw carefully making

sure you do not overtighten it.

Fit the drive belt around the subplatter and the pulley. Again, use a piece of paper or cloth to avoid soiling

the belt. Replace the platter.
