Shown below are scanned copies of the Amiga schematics I have in my collection. Whilst there are searchable schematics online at AmigaWiki, you will find the information in some areas, have errors, notably in the audio circuits. Some of the discussion is here on EAB, https://eab.abime.net/showthread.php?t=109051&highlight=amiga+audio+circuit
