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.

11. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000 Hz ± 5 Hz (FWD). 12. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the 8 kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 13. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8 (Lch), TP9 (Rch) Method : Play back the 315 Hz and 8 kHz signals of the test tape and check that the output ratio of the 8 kHz signal with respect to that of the 315 Hz signal is 0 dB ± 5 dB. 14. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP8 (Lch), TP9 (Rch) Method : Play back the test tape and check that the output level of the test point is 110 mV ± 3 dB. 15. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8 (Lch), TP9 (Rch) � Input signal : 1 kHz / 8 kHz (LINE IN) (-20VU) � Adjustment location : SFR451 (Lch) SFR452 (Rch) Method : Apply a 1 kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes 0 dB (10 mV). Record and play back the 1 kHz and 8 kHz signals and adjust SFRs so that the output of the 8 kHz signals becomes 0 dB ± 1 dB with respect to that of the 1 kHz signal. 16. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8 (Lch), TP9 (Rch) � Input signal : 1 kHz (LINE IN) (0VU) Method : Apply a 1 kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP8, TP9 becomes 0 dB (100 mV). Record and play back the 1 kHz signals and check that the output is -1 dB ± 3.5 dB.
