Akai M6 Schematic Service Manual Needed

[FPALB]

Just had one of these come in and seeing that its probably got some similarities with the M8(7), but wanted to ask if anybody has any access to an M6 schematic.

Thanks.

I have an Akai Terecorder Deluxe that I understand is pretty similar to the M-6.
Schematics only in the Teracorder manual, copied here.
