time,
it may
be necessary
to
replace
pots,
jacks, the
display,
or
other components. When

use
all
caution
to
prevent
damage
to
the circuit
board,
traces
and pads.
When

sure
that
they
are
mechanically
flush
with the circuit
board
prior
to
soldering
in

stress can
be
placed on the new
components
and
the
board
—
resulting
in
early
failure
of the board and/or
component.
