If noise is heard from new discs, the stylus is probably worn.
Replace it with a new one.
(Refer to the operating instructions of the cartridge.)
The plug-in type of cartridge is already designed to match this
unit in every respect: weight, correct stylus pressure, stylus tip
position, center of gravity, etc. This means that there's no longer
any need for troublesome connection of lead wires or
adjustment of the stylus pressure.
(Refer to page 3.)
When the platter rotates, the strobe marks form a stripe pattern
according to the rotation speed and the frequency of the power
supply.
The platter speed is correct when the stripe pattern of the
stroboscope appears to be stationary while the platter is
moving; adjust the speed if the stripes appear to be moving.
