FM frequencies, by their very nature, require careful placement of parts and leads. In conventional point to point wiring, misplacement of a wire, even a slight amount from its correct position will adversely affect operation. The amplifier has been designed to use printed circuits in those areas where each component and each connecting lead must be carefully positioned in order to afford best possible operation.

THE
CODA
These
photographs
show
the
printed
circuit
boards
used
in
the
Harman-Kardon
Coda
and
indicate
to
some
degree
the
complexity
of
design
and
painstaking
care
required
in
the
planning
of
such
a
unit.
FM
frequencies,
by
their
very
nature,
require
care-
ful
placement
of
parts
and
leads.
In
conventional
point
to
point
wiring,
misplacement
of
a
wire,
even
a
slight
amount
from
its
correct
position
will
adversely
affect
operation.
The
amplifier
has
been
designed
to
use
printed
cir-
cuits
in
those
areas
where
each
component
and
each
connecting
lead
must
be
carefully
positioned
in
order
to
afford
best
possible
operation.
This
design
form
results,
we
feel,
in
providing
the
best
possible
characteristics
and
reflects
the
highest
state
of
the
art
in
the
construction
of
fine
audio
equip-
ment.
