Luxman Hifi schematics

[Aurora]

While I'm at work, and not being able to do much else than waiting, I did some googling, and found some rather foggy and unreadable schematics.
Seems there are mainly two versions . one seems to be a rather comman Baxandall in between two sections as in the block diagram, but with switchable freq and a middle flat position The other rather newer version is a typical tone tilt ala Quad......
The Baxandall should be fairly easy to recalculate to include the switching...
The old Quad 22 preamp have a rather interesting tone section, though....
lost the link -- schemo available on the net.....

Not sure the difference in these schematics.

The LUX tone control isn't the same as the Baxandall tone control, it's a bit simpler and uses less parts. The part values for the LUX tone control can be seen from the third schematic posted above.

Anyone have a Luxman L-504 schematic that they can post ?
