Clear and complete service manual. Easy now to restore my old Kenwood KD-1500.
Thanks a lot.

Thanks for this "hard to find" service manual. This Sony PS212A is a very good turntable that needed to be restored !

Excellent quality on these manuals. Same as having the original printed manual and incredibly useful when doing a custom install like me. Keep it up on the good work.

This is an excellent information source. Great quality and tons of info regarding technical service for the Technics SH8065.

5 stars on this manual since it is the complete version, not the half manual you find free for download all over the web. Good job.
