Excellent manual, detailed, very useful! Exactly what I needed, I'd recommend it to all who need it. Although images are scanned easily readable and explicit. A valuable tool product at a price more than modest, take it with confidence and you will not regret it!

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.
