Some pictures from this page onward are the ones
of the off-line job when the head is removed, and
are different from those of the on-the-machine job.
When replacing the amplifier, do not remove the
head from the machine; it should be replaced with
the head on the machine.
The job procedures are the same as those for the
off-line job.
Disconnect CNs 39 and 40.
