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.

Content A4 and A3 format pages. Exactly what I needed to restore my old receiver.
