The
upper
loop
forming
system
is
improved
forming
and
keeping
a
larger
upper
loop.
The
lower
loop
forming
system
is
improved
forming
and
keeping
a
larger
lower
loop.
Sound
drum
system
like
“М”
series
is
used.
The
conventional
rubber
pinch
roller
has
been
deleted
and
the
buzz
roller
with
tension
spring
loaded
activates
also
as
the
pinch
roller
on
the
sound
head.
.
Wow
and
flutter
is
minimized.
The
adjustment
of
wow
and
flutter
is
easier
since
less
parts
are
used
in
the
film
path
near
the
sound
head.
.
The
rear
dampening
tension
roller
is
given
more
allowance
to
move
freely
to
absorb
the
jerky
take-up
and
minimize
wow
and
flutter.
.
The
flywheel
brake
is
added
to
stop
instantly
the
flywheel
and
the
sound
drum
rotation
at
"STOP"
position.
.
The
front
cover
is
fitted
firmly
on
the
projector
so
that
the
cover
would
not
come
off
too
easily
in
transit
or
when
the
cover
is
pushed
up.
.
The
lamp
house
door
has
more
ventilation
holes
on
its
top
to
cool
down
heated
parts
more
efficiently.

Amplifier
control
knobs
have
better
looking
and
are
easy

.
Control
knob
of
the
function
rotary
switch
is
mounted
more
firmly
avoiding
slippage
on
the

shaft.
