Replay at 78 r.p.m.
** 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..
Fitting the 78 r.p.m. pulley
Before beginning work fit the cartridge’s needle protection cover.
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.
