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.

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.
Adjust the Purity rings to set the vertical green raster precisely at the center of the screen (see Fig. 12).
NOTES: 1. CRT warm up with white screen (three guns activated) is needed to stabilize the shadow mask expansion. 2. Initial center static convergence (roughly centers three gun beams) is required in order to perform purity adjustment.
Figure 12. Green Raster Adjustment
Green Raster
Slowly move the deflection yoke forward until the best overall green screen is displayed. Tighten the deflection yoke clamp screw. Press the Recall button on the Remote Control again until the purity check (blue screen) and (red screen) appear and observe that good purity is obtained on each respective field. Press the Recall button on the Remote Control again until Purity check (white screen) appears. Observe the screen for uniform white. If purity has not been achieved, repeat the above procedure.
Align The converged red/blue dots with the green dots at the center of the screen by rotating the R&B&G pole Static Convergence Magnets. Melt wax with soldering iron to reseal the magnets. Slightly tilt vertically and horizontally (do not rotate) the deflection yoke to obtain a good overall convergence. If convergence is not reached at the edges, insert permalloy (see following section) from the DY corners to achieve proper convergence. Recheck for purity and readjust if necessary. After vertical adjustment of the yoke, insert wedge at 11 o�clock position, then make the horizontal tilt adjustment. Secure the deflection yoke by inserting two side wedges at 3 and 7 o�clock positions. Apply adhesive between tab (thin portion) of wedge and CRT and place tape over the tab to secure to the CRT.
Permalloy Convergence Corrector Strip (Part No. 0FMK014ZZ)
This strip is used in some sets to match the yoke and CRT for optimum convergence. If the yoke or CRT is replaced, the strip may not be required. First converge the set without the strip and observe the corners. If correction is needed: 1. Place strip between CRT and yoke, in quadrant needing correction. Slowly move it around for desired results. 2. Press adhesive tightly to the CRT and secure with tape.
Final Convergence Procedure (see Fig. 13
through Fig. 15):
Note: Vertical size and focus adjustments must be completed prior to performing the convergence adjustment. Connect a dot pattern generator to the Receiver. The Brightness level should not be higher than necessary to obtain a clear pattern.
Converge the red and the blue dots at the center of the screen by rotating the R&B pole Static Convergence Magnets.
