Dynamax DAX 15 Pro - Help needed in finding a Service Manual

[Alektron]

A friend of mine from Europe asked me if I could find him a service manual for this karaoke amplifier receiver that needs repair.

I searched the internet but I couldn't come up with anything. I was wondering if someone might be able to help me out from the forum, I would really appreciate it.

Thank You.
