Not sure but one of the routers on the site references a template set 9 2573 without the slash, if you search on the top search box on the homepage is should bring up the link for you to the router.

The STR-K9900P appears to have been originally part of a whole surround sound system, that manual mentions different model numbers on the cover, which are the systems it came with, but if you look in the manual, it covers the STR-K9900P as part of those systems. Thanks

This manual has been located, thus the upload option is no longer available.
Can not find a manual but you can go to http://www.searspartsdirect.com/partsdirect/getModel!retrieve.pd?modelNumber=502.25900&pathTaken=partSearch to see diagrams at least. Thanks
