Clear and complete service manual. Easy now to restore my old Kenwood KD-1500.
Thanks a lot.
;
Thanks for this "hard to find" service manual. This Sony PS212A is a very good turntable that needed to be restored !
 ;
Excellent quality on these manuals. Same as having the original printed manual and incredibly useful when doing a custom install like me. Keep it up on the good work.
;
This is an excellent information source. Great quality and tons of info regarding technical service for the Technics SH8065.
;
5 stars on this manual since it is the complete version, not the half manual you find free for download all over the web. Good job.

2. Set the pattern generator raster signal to green. 3. Move the deflection yoke to the rear and adjust with the purity control so that the green is at the center and the blue and the red take up equally sized areas on each side. (See Figures 3-1 through 3-3.) 4. Move the deflection yoke forward and adjust so that entire screen is green. (See Figure 3-1.) 5. Switch the raster signal to blue, then to red and verify the condition. 6. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws. 7. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.)
