No. But several years back I contacted Focusrite support about a Mixmaster. They offered superb repair support for free back then, including selling replacement optocoplers for little money.
No schematic, but a very detailed troubleshooting walkthrough (with component values and numbering, first measure here, then check there) that was tailored to the exact problem of the unit on my bench.
Not sure about their support today but can't hurt to contact them.
