Default Tube/SS Power Amplifier Audiotec Fischer Esprit Helix E40 - Schematic wanted

Tube drived solid state car hifi power amplifier Audiotec Fischer model "Esprit Helix E40"

I am looking for a schematic. I need this schematic for troubleshooting (sometimes shot noise at one channel).
The manufacturer offer only an instruction manual (German and English) - go to

Thank you for upload.

Maybe there are other OEM brands, where the same PCB is in use (have a look to the attached files)
