Kenwood KT-52 Service manual wanted

Hello to all fellow members. A Kenwood tuner KT-52 came to my hands with Power Supply problem.
Allthough I repair this section, it is not working as expected. Also it is set to tune in USA frequency steps. I would appreciate if someone of you has this munual or if can guide me to change step to European standards.
Thanks in advance for your kind attention and help.
Regards from Greece,
