Editing Macintosh Classic (section)

== Maintenance, capacitors and troubleshooting ==

* '''[[Macintosh Classic / Classic II General Maintenance]]''' — cleaning, the 3.6 V lithium cell and its 3.0 V replacement threshold, and what Apple does and does not publish about the rails.
* '''[[Macintosh Classic Capacitor Replacement Guide]]''' — values and positions.
* '''[[Macintosh Classic / Classic II Troubleshooting]]''' — symptom-led diagnosis.
* '''[[CRT Discharge Procedure]]''' — read before opening the case.
* '''[[Retrobrite]]''' — for the yellowed case.

'''Apple publishes no rail tolerance and no power-supply adjustment for this machine.''' Its Adjustments chapter is video and yoke work only — light meter setup, cutoff, brightness and contrast, centring, size, focus.<ref name="sscl" /> Note also that ''The Dead Mac Scrolls'', the standard component-level reference for the earlier compacts, explicitly does not cover the Classic.<ref name="dms">Larry Pina, ''The Dead Mac Scrolls'', Peachpit Press, 1992, introduction.
