Fostex 450 mixer service manual / schematics needed

[tmuikku]

Yello fellows! I need schematics for Fostex 450 mixer. Available only for 45$ from a manual service found online... absurd price, more than the machine itself hehe.

Owners manual can be found here http://www.fostexinternational.com/docs/downloads/pdfs/450_owners_manual.pdf

I recently purchased one to pair a 4-track cassette recorder for bedroom stuff and need to see what is going on inside.

Thanks!
