Default Alesis M1 MkII - any schematics or BOMs?

This is a long shot (and mods, please let me know if this is too far off-topic), but...
One of my old (probably 1st-gen) Alesis M1's let all the smoke out. I found a few helpful things online about the C8 and R4 problem, but this is a bunch more than that. I counted 3 resistors and a cap that fried (thus protecting the fuse).

The problem is that I can't get a schematic from Alesis. I found one online somewhere but the resolution's too low to see part values and locations. I even checked out replacing the whole board, but the part alone is $150. Anyone have a schematic or a BOM for these?

Thank you sir!. Very much appreciated, but the schematic (p. 6) is the low-res one I was talking about. No matter how much I zoom in, I can't read any part values or even location designators. Thank you, though.

Could there be a problem with your pdf reader?

I've used this SM to repair one of these (blown PSU) and I could zoom in perfectly. I'm on a Mac, using the built-in pdf reader.

Thanks, I'll try a few things.

Thank you. I did see that one, and it's a good fix for what I call the "the C8 /R4 problem". I did find a solution, though... bought a new pair of monitors.
