Thirty
years' experience
as
high
fidel-
piece
of
equipment shown
on
the
followingpages.
Thirty
years
in
which
Sansui
has
acquired
an
enviable
reputation
for
unvarying
qual-
ity
and advanced
engineering design.
Our
initial
product,
a
power
trans-
former
designed
to
meet exacting
pertor-
mance and
reliability
specifications, estab-
lished the standards against which
every
subsequent
Sansui
product
has
been meas-
ured. Consistently
meeting rigourous qual-
ity
standards
has
repeatedly
led us back
to
re-think
the
basic
design
of
electronic
com-
ponents and electro/mechanical systems
in
terms of
the specific
role
each
plays in
the
accurate
reproduction
of music.
The
result
of
our
fresh
approach has been
a
series
of
innovations placing
Sansui,
year
after
yeax,
in
the
forefront
of
state-of-the-art
audio engineering
attested to by
an
impressive
list
of
world
wide patents and
-
the
high
esteem of
hi-fi
experts
and
en-
thusiasts
ever5rwhere.
Developing expertise in
manufactur-
ing techniques alongside
advance
design
has
consistently
enabled
us
to rapidly
in-
corporate the latest technology
into
our
full
range of
equipment. From
the moderately-
priced,
to the
top
of
the
line components,
you
can
always
be
certain
youle getting
the highest
reliability
and accuracy
in
sound

for
your money.

exclusively
on
