Sansui Au-10000

Hi I'm trying to track down a copy of a service manual or any other info on the rather rare Sansui au-10000. This amplifier was released in Japan only around 1977. It is similar to the au-9900 and Au-11000.

Here's a few links to the limited information I have found:

Any help appreciated.

Thanks.
