sansui 5050 voltages on schematic

Hi, new member here...I'm working on a Sansui 5050 that has a variable distorted output...downloaded the schematic from this website, thanks! Problem is, the voltages on the schematic look like they were originally in color and are obscured by black oval blobs in the black and white scan. Does anyone know of a color scan or know what the voltages are?
