Changing the frequency
To change frequency, it is necessary to
change the motor pulley which is secured
to the motor shaft by a screw. For access
to the motor pulley the platter must be
removed.

Extreme care is necessary when changing
the motor pulley, as a bent motor pulley
will cause rumble.
Part numbers for motor pulleys:
50 Hz: 220 418
60 Hz: 220 419
Removing the platter
The platter is supported by means of a
spring disc secured by a nut that sits
on the platter cover. To remove the plat-
ter, first remove the platter cover, then
the spring clip can be removed.
Important: When handling the platter
avoid touching the inner surfaces
with your
fingers as skin oils can cause slippage
(and resulting pitch deviation) between the
idler wheel and the driving rim of the
platter.
