Yamaha RX-V1079 / RX-A1050 service manual, schematics

[Mark_dk]

Hi,
I'm looking for the schematics for the Yamaha RXV1079 AV receiver. I believe it is the same internals as the RXA1050 so this would also be an option.
The unit is rather new (2015) and there is nothing wrong with it. Looking to do some modifications and upgrades to the analogue section.
The schematic would make this quite easy. Thanks a lot for your contribution. Any advice, links, or site where I can buy this manual would be greatly appreciated.

Thanks!
