Service Manual that I received was very helpful to me. Thank you.

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.

Acurate informations inside the SM and I could repair my old Sansui SC-3330 without any problems. Thanks.
T D A 8374 has a black current stabilization loop, that autom atically adjust the black level to the cut-off voltage of the picture tubes three gun cathodes. S ince no current is flow ing w hen the voltage the cathode is equal to the cut-off voltage of the tube, the loop stabilizes at a very sm all gun current. T his �black current� of the three guns is m easured internally and com pared w ith a reference current, to adjust the black level of R G B out. T he black level loop is active during 4 lines at the end of the vertical blanking. In the first line the leakage current is m easured (m ax. acceptable 100
