Very good quality original datasheet!I like this amazing website!!!!!!
 ;
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.

IC952 (Pin 14)
Step 6: DIR
Check that the SPDIF signal is output. Check that changes by pulling out and inserting the digital input lines. IC601 (Pin 1) No Replace IC952. Can No Check the DIGITAL INPUT Assy, observe the digital signal and parts and patterns in the path. ? (0 V � 4 V) Yes IC601 (Pin 5) IN2 (OPT: CD-R/TAPE/MD) IN1 (OPT: TV/SAT)
A
Do convert 3 V into 5 V for pin 6 input? Yes IC952 (Pin 13)
Do convert 3 V into 5 V for pin 7 input? Yes To Step 5
No
Replace IC952.
