On head cleaning
The
best
performance
of
your
unit
is
dependent
on
the
periodic
cleaning
of
the
heads
and
all
surfaces
over
which
the
tape
travels.
Dirty
heads
and
tape
path
cause:
Loss
of
high
frequency
response
Loss of sound volume
Sound drop-outs
Cleaning
should
be
done
every
after
10
hours
of
operation.
For
