Excellent just what I needed to replace the electrolytic caps and make this old gem a beauty again. Was as scan of the original photocopied service manual.
;
It was helpful to get schematic with waveforms in important points and lot of service information. Manual is good quality, fast delivered. Of course it is hardcopy of paper one with all its disadvantages.
 ;
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.

Complete manual including mechanical part in good pdf quality. Shaded greys of the pcb due to pdf not perfect but usable.
[Dynamic Convergence Adjustment] 1. Minimize the vertical misconvergence in the left-most end of the center of a screen and in the right-most end of the center of a screen by adjusting the DY correction reactor XCV as shown in Fig. 1-15. 2. Minimize the vertical misconvergence in the top of a screen and in the bottom of a screen by adjusting the DY correction reactor YCH as shown in Fig. 1-15. 3. Minimize the vertical misconvergence in the top of a screen and in the bottom of a screen by adjusting the DY correction reactor TLV as shown in Fig. 1-15. 4. Minimize the vertical misconvergence in the left-most end of the center of a screen and in the right-most end of the center of a screen by adjusting the DY correction reactor TLH as shown in Fig. 1-15.

[G2 Adjustment] 1. Connect the 480/60i entire black signal to the ANALOG Y/G input connector. 2. Connect an oscilloscope probe one after another to the C board R-cathode (TP701), G-cathode (TP702) then B-cathode (TP703) to measure the DC voltage at their respective pedestal portion. 3. Connect an oscilloscope to the cathode whose DC voltage of the respective pedestal portion has the highest DC voltage. 4. Adjust RV702 on the C board so that the DC voltage of the respective pedestal portion is 125 ± 3 V.
