Dokorder 7010 service info

Hi, I am new around here, but have kicked around the audio world for a while now.

I picked up/rescued a Dokorder 7010 from the side of the road a while ago. It is complete, and it runs, records and plays poorly, but gets very distressed, hot and smelly, very quickly.

Could anyone help me with a service manual or schematic for this monster, or maybe one of its siblings?
