Kurt's tech told me that to replace the laser in the CDX-10000 with the HG-1 requires some additional parts and the supplemental service manual.
I called Yamaha parts and spoke to a service tech who just happened to be very familiar with the CDX-10000 and replacing the original laser block with the HG-1. He confirmed that there were a number of other parts needed to do the repair, and access to the supplemental service manual. Unfortunately, neither the parts or the SSM are available. I managed to talk him into selling me the service departments own service manuals for the CDX-10000.
So I now have the service manual and supplemental service manual for the CDX-10000.

The HG-1's can be used for my CDX-1100 and CDX-2200.
