Looking for a schematic for the TU-8500 Preamp

Bought an assembled preamp from another forum member. One of the non-phono inputs has some issues (left channel is out, right channel level is low). I have a friend that is an electronics tech and I am going to ask him to see if he can fix it. Does anyone have a schematic?
