This monitor has a separate power supply board that Apple treats as its own replaceable module, which the 12-inch monochrome display does not - the two manuals are not interchangeable even though the tube size matches.
What this manual does not contain
No parts list, no schematic, no component values, and no fuse rating. The Adjustments chapter covers geometry, focus and video; no supply-rail voltage or tolerance is printed.

A CRT display holds a lethal charge on the anode after the mains is removed. Follow CRT Discharge Procedure before working inside one. Apple's own Take Apart chapters open with the same warning.
