Teac A-H400

Hi all,
Have just been handed the above amp by a friend, just before Christmas!, and looks like her party will be going down a flop. Does anyone have a service manual please.

Looks like a straight forward problem, possibly the power on relay or thermal fuse, just need to see how its wired without taking the thing apart and doing a manual circuit trace.

Thank in advance and seasons greetings to all.
