Here,the bias,DC Offset and schematic diagram of the Sansui AU-999
But it's a little tricky,
1.to get this schematic (i explain how to)
2.to adjust the bias,(i need a picture)
Donload the bias adjustement procedure (a real .pdf file) -> AU-999.pdf
Due to the max size of files attachement,i compress the file at the maximum possible with paq8px and i renamed it (.pdf)
1st,download on your desktop and rename the file -> schematic.paq8px.pdf into -> schematic.paq8px
2nd,download on your desktop and extract paq8px: http://encode.ru/attachment.php?attachmentid=1275&d=1272306083
3rd,drag and drop the file schematic.paq8px over -> paq8px_v69.exe
A folder (containing the file Sansui_AU_999_Schematic_Diagram.jpg) will be extracted on your desktop.

I have used the method from EchoWars here http://www.audiokarma.org/forums/showpost.php?p=1605892&postcount=2
But i want to try the method specified by Sansui,
the method is explicated in an unusual way and i don't want to make any mistake,so please,give me a picture.
Just test on the fuse socket?
When looking under the chasis,the fuses sockets connections for F003 (Left channel) and F004 (Right channel) did not compared.
I burned a couple on mA tester fuses trying this,(before deoxitysing the pot)
I just don't want to repeat this episode.
