Perfect quality. Was able to fix speed drifting on my Sansui Turntable using the service manual instructions for PLL adjustment.

I am very happy regarding the online purchase of this manual from Owner-Manuals.com as with this I could set right my Denon CD player and Amplifier.
I once again sincerely thank them for the prompt service which was rendered to me.

More than pleased with my prurchase, very good product for the price.

Manual-link came 30 minutes after having paid for an extremely rare (40 years old) item (sony icr-120) and helped me to get the radio rework again. So really good help for me, fast and reliable delivery and -taken that into consideration- a very reasonable price for that service. So thanks again! Mike, Germany

Some of the pictures in this manual are a bit irritating. I had to dissassemble the unit and some of the screws have different threads, which is not mentioned in this manual. Also some of the drawings of the boards look different than the actual boards.
After all, the manual was very useful. I was able to recalibrate the capstan drive and it is working fine again.
