The manual is well organized and is easy to read. The chapters are following normal way to proceed.

This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.

I used it to repair a NAD 7030, but unfortunately, the 7045 is different !
But documentation was useful.
