Issue
-----
The Mac OS 7.6 installer incorrectly installs two additional control panels, 'Monitors' and 'Sound' on PowerBook 1400 series computers if you choose the Easy Install option, and are installing over an existing System Folder. You only need the one control panel, 'Monitors and Sound'. You can throw the other two away. All of these control panels work, but only the one which controls both the Monitors and Sound is needed.
If you are creating a new System folder (clean install) and you choose the Easy Install option, the Mac OS 7.6 installer incorrectly installs two separate control panels: 'Sound' and 'Monitors.', NOT the one 'Monitors and Sound'.
Resolution
----------
To get the correct Monitors and Sound control panel, you must perform a Custom Installation in which you specifically select the desired control panel.
