Topic: Anyone know where to get Sansui 9090db Schematic

[Sparge Master]

Hey ya'll I want to fix a Sansui 9090DB receiver I got for free but I cant find a schematic online for it. I get cutout in the sound and read before it can be caused by the dolby shit in the unit. I am gonna go to rat shack and get some cleaner for the pots and if that doesnt work then I might have to open her up but want a schematic before I do.

Thanks
