I already have a copy of the manual, and there are conflicting information about the value of this resistor between schematics and parts list.
I have posted on the Sansui forum a question to help me restore a Sansui 3300, and someone (Avionic) pointed that you may have one.
So, do you have access to a 3300 ?
If so, could you take a look at the driver board, and tell me what value is R816 ?
Here is a pic to show the part: http://www.casimages.com/img.php?i=090610074631411213837233.jpg
