Needed: Bell 7007 / Fostex 800 ?? schematic/service manual

Got my hands on a Bell 7007 Power Amplifier (should have been build for Bell by Fostex and be the same as a Fostex 800 Power Amplifier), and It needs a complete overhaul.
Can't find either the schematics or the service manual though....
Any kind soul here that has it it would like to share with me??
Thanks in advance.
