I want to give you a real heads-up for your desire to enable such people as I to acquire the information I need to maintain the older types of equipment such as this Akai HXA351W. You do a swell job with all the processes you have to perform so I can have a legible, thus usable
document which does not send me crazy trying to figure out the blurry text of a bad copy.
Very well done, Thomas.

This manual is very well presented and after printing out looks about as close to an original as I think you can get. The quality is second to none.
The content of the manual is comprehensive and I think it would be well suited to an audio repair professional which I'm not but I did find it very informative and helpful.
The cost of the manual is more than covered by the money I'll save when I change the keep memory battery now I have the relavant info.
Very pleased with my purchase and can recommend it wholeheartedly as I can other manuals I've downloaded from this site.
Regards
Limey Alex

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 switches 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 set's power and degauss with the degausser.
Neck assy DY
3-1. BEAM LANDING
1. Input a white signal with the pattern generator. Contrast normal Brightness
}
Note: Neck Assy is exactly behind DY (no gap between Neck Assy and DY)
2. Position neck assy as shown in Fig3-2. 3. Set the pattern generator raster signal to a green raster. 4. 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.) 5. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 3-1.) 6. Switch the raster signal to blue, then to red and verify the condition. 7. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws and DY spacers. 8. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.)
