                        The first
                        step I use in dismantling the unit is to
                        separate the head and primary valve chest
                        from the secondary valve chest and the
                        pneumatic boards. This picture
                        illustrates how the complete unit looks.

                        This is what
                        the secondary valve chest and the
                        punmatic boards look like after the head
                        and the primary unit has been removed.

                        Here is the
                        picture of the head and primary valve
                        chest. The board that is hanging off the
                        table is called the "L"
                        channel. It channels the primary reduced
                        air signals to the pouches of the
                        secondary valve unit.

                        It is now
                        time to remove the head from the primary
                        valve chest. The head is the shelf that
                        sits on top of the primary valve chest
                        and contains the spool box, transmission,
                        automatic tracking device and the wind
                        motor. As you can see in the picture you
                        must break the lead tubing away from the
                        junction board before you can remove the
                        head from the chest. Here you can see
                        about half of the tubing has been broken
                        loose.

                        Notice two
                        things about the lead tubing. First it is
                        cloth covered. This is an extra and was
                        done on your nicer player units to dress
                        them up. It serves no mechanical purpose
                        except to give a little protection to the
                        lead. Second notice the white stuff
                        inside the tubing. This is lead oxide and
                        one should be very careful while handling
                        the this tubing.

                        With the
                        tubing broken loose and the screws
                        removed the head can be lifted away from
                        the chest and set aside. As you look at
                        the primary valve chest you will notice
                        where the tubing was connected at the
                        rear and you can see the "L"
                        channel board on the front.

                        Now the upper
                        player action is divided into three major
                        sections. 1. The head, 2. The primary
                        chest, 3. and the secondary chest and
                        pneumatic decks. It is now time to
                        disassemble these 3 individual units.
