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.

2.3.3 Removal/Reattachment of Acoustic absorbent pads
A
Removal/reattachment of acoustic absorbent pads is necessary before or after removal/reattachment of the Network Assy. Note: When reattaching the Network Assy for the midrange/tweeter, before reattaching the closure panel, be sure to remove the acoustic absorbent pads located behind the chamber. (See Fig. 2-11.) If the closure panel pinches an acoustic absorbent pad when it is secured, air leakage may occur, which may result in poor performance of this speaker system. 1. Acoustic absorbent pads around the input terminals 2. Acoustic absorbent pads inside the chamber for the midrange/tweeter
1 Remove this acoustic absorbent pad. When reattaching, lay it along the upper board inside the chamber.
B
1 Remove this acoustic absorbent pad. When reattaching, roll it and push it in under the reinforcing plate. As only this acoustic absorbent pad must be fixed with adhesive, before pushing it in, apply adhesive to the side board of the cabinet. (Adhesive: DIABOND black/GYL-014)
2 Remove this acoustic absorbent pad When reattaching, place it along the surface inside the chamber so that it forms a U shape.

C
2 Remove this acoustic absorbent pad. When reattaching, push it in along the lower surface of the reinforcing plate. Fold the remaining part of the pad toward the bottom board side so that it forms an L shape. The cords from the input terminals must be pulled out from the upper side of the acoustic absorbent pad.
3 Remove this acoustic absorbent pad from the closure panel section. When reattaching, fold it in half lengthwise and push it in.

3 Remove this acoustic absorbent pad. When reattaching, fold it in half lengthwise and push it in.
3. Acoustic absorbent pads around the Network Assy for the midrange/tweeter
4 Do not remove the acoustic absorbent pads around the Network Assy for midrange/tweeter. Remove the 2 rolled acoustic absorbent pads stuffed behind the space of the chamber for midrange
/tweeter.
Insert your hand in the direction of the arrow to remove.

Removal/reattachment of the Network Assy for the midrange/ tweeter and of the closure panel must be done in this state.
E
In this state, remove or reattach the Network Assy.
Fig. 2-11: After the upper woofer is removed
When reattaching, lay one acoustic absorbent pad on another and roll them, and make 2 rolls of acoustic absorbent pads. Place one roll lengthwise, push it into the front of the top board of the cabinet, then push another beneath of the first one.
