Another schematic request...Neve 8816

[km6xz]

I am looking for a hard to find schematic, the Neve summing amp 16 to 2 channel model 8816. I contacted Neve and they say they do not let out schematics but I know they have warranty stations. It is a complex item for such a simple function with hundreds of SMD chips and no markings of any parts on the pc board, mostly 5534, 5532 and some 8 pin chip with a house number on it. I was hoping someone in a warranty station would be able to shed some light on it.
Thanks
