Welcome to PF.

It looks like your question on allaboutcircuits.com isn't getting replies either. If you can't find it with a Google search (like I'm not able to find it), then most likely the schematic is proprietary. Why are you wanting a schematic? Do you need to fix one, or are you trying to reverse engineer it?

i want to fix a related amp

I don't know what that means. Which "related amp"?

Fault finding does not usually need a schematic diagram.
Most amps are the same on the inside with only minor changes.

What power transistors are used, and how many per channel ?
Do you know when it was built, date codes ?
Can you produce a photo of the circuit board and the power supply.

What are the symptoms ?
There are several people on this forum who can tell you what to check next.
