Excellent manual, very clear, technical specification provided, useful information regarding adjustment and set up.
 ;
fast and easy and exactly what I was looking for. Not the cheapest but value for money after all.
;
The manual for the Sansui P-L75 was not one of the more informative turntable manuals around but for $5 it was helpful enough.

SECTION 3 SET-UP ADJUSTMENTS
� �
The following adjustments should be made when a complete realignment is required or a new picture tube is installed. These adjustments should be performed with rated power supply voltage unless otherwise noted.
Perform the adjustments in the following order 1. Beam Landing 2. Convergence 3. Focus 4. White Balance Note : Test Equipment Required: 1. Color-bar/Pattern Generator 2. Degausser 3. Oscilloscope
Controls and switch should be set as follows unless otherwise noted: PICTURE control ........................................................... normal BRIGHTNESS control ................................................... normal
................................................................................................................................................................................................................................
Preparation : � � In order to reduce the influence of geomagnetism on the set's picture tube, face it east or west. Switch on the power and degauss with the degausser.

3-1. BEAM LANDING
1. Input a white signal with the pattern generator. Contrast Brightness

normal
2. Set the pattern generator raster signal to a green raster. 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 the 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 screw. 7. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.)
