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.

Very useful service manual, was exactly what i needed.Good quality,reasonable price.Thank you.

Acurate informations inside the SM and I could repair my old Sansui SC-3330 without any problems. Thanks.

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.

1.3.8 Coefficient display of adjustment results
For some of the adjustments (FE and RF offset, FZD cancel, F and T gains, and RFAGC), the adjustment results can be displayed and confirmed in the test mode. The coefficient display in each auto adjustment is as follows: 1) FE and RF offset Reference value = 32 (coefficient of 32 indicates that no adjustment is required) The value is displayed in the unit of approximately 32 mV. Ex. When the FE offset coefficient is 35, 35 - 32 = 3 x 32 mV = 96 mV The correction is about +96 mV, which means the FE offset before adjustment is - 96 mV. 2) F and T gain adjustment Reference value for focus and tracking = 20

The displayed coefficient / the reference value indicates the adjusted gain. Ex. When the AGC coefficient is 40, adjustment of 40 / 20 = 2 times (+ 6 dB) has been performed. (It means that the original loop gain was half the target, and the whole gain was doubled to obtain the target value.) 3) RF level adjustment (RFAGC) Reference value = 8 The coefficient of 9 to 15 indicates to increase the RF level (for more gains). The coefficient of 7 to 10 indicates to decrease the RF level
C
(for less gains). When the coefficient changes by 1, the gain changes by 0.7 to 1 dB. When the coefficient is 15, the gain is the maximum at TYP + 7.9 dB. When the coefficient is 0, the gain is the minimum at TYP - 4.6 dB.
