Pitch-control
Each of the three standard speeds (33'/s,
45 and 78 rpm) can be varied about 6%
(epproximately
one
musical

‘The speed can be checked with the stro-
boscopic
disc
on
the
turntable
platter.

When the disc is illuminated by a light
(preferably
fuorescent)
powered
from
alternating household current, the ring of
lines corresponding to the choosen speed
will appear to stand still when the turn~
table is rotating at the correct speed.
‘Adapting

To
adapt
the

frequency,
is
accomplished
by
