The schematics displayed are for the original Project-o-Sonic version, with half-coil Filtertrons and 3 switches + 2 volume controls. This was the version used on the Brooklyn era Anniversary, White Falcon and Country Club models.
The one pictured in the OP's original post is a later 5-switch model, which has a completely different schematic. I have yet to even find a schematic for the 5-switch version.
