WIRING
These
instructions frequently specify
that
you
twist to-
gether some wires.
This
twisting should
not
be done too
tightly
or
the
wire
may
cut
through
the
insulation.
The
twist
is
sufficiently
tight
as
long
as
the
wires
are
neat
and
will remain together;
there
is
no
need
for excessive twisting.

manner
in
which
the
PEC-555002 tone control modules
are
wired to
the
bass, treble,

volume controls. Begin
by
carefully Gutting
the
leads of
one
of
the
circuit
modules exactly to
the
following lengths; slip black
insulating sleeving on the leads
as
specified.
The
PEC

that
the

marked
on
it
are
visible; this
module
connects to
terminals
nearest
to
the
front panel. After
all
connections
are
made
to
the

the
second module will be placed
flat
against
it
in
the

and
its
