Discrepancies between the Sansui schematics and the actual physical circuit are rather common. In most cases it is due to changes during the production run. I think that you are referring the R32 and not R34. The 0.33µF film capacitor across R32 is stock (I did not add this capacitor). As for R32, but I cannot confirm that it is 180ohm or 270ohm (since I don't have any pictures that show this clearly and the unit is back with its owner).
