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.

Service hints CAUTION
10-2
CHARGED CAPACITORS ON THE SERVO BOARD MAY DAMAGE THE CD DRIVE ELECTRONICS WHEN CONNECTING A NEW CD MECHANISM. THAT´S WHY, BESIDES THE SAFETY MEASURES LIKE � SWITCH OFF POWER SUPPLY � ESD PROTECTION ADDITIONAL ACTIONS MUST BE TAKEN BY THE REPAIR TECHNICIAN.
The following steps have to be done when replacing the CD mechanism: 1. Disconnect flexfoil cable from the old CD drive 2. Put a paperclip on the flexfoil to short-circuit the contacts (fig.1) 3. Remove the old CD drive 4. Remove paperclip from the flexfoil and connect it to the new drive 5. Position the new CD drive in its studs 6. Remove solder joint from the Laserunit
fig.1
Attention: The laser diode of this CD drive is protected against ESD by a solder joint which shortcircuits the laserdiode to ground. For proper functionality of the CD drive this solder joint must be removed after connection the drive to the set.
Emergency open
In case of a Supply fault, the tray can be opened manually. 1. Remove the top cover of the set to get access to the Changer Module. 2. Turn gearwheel clockwise (as shown in picture below).
