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.

ANODE LEAD REMOVAL
CAUTION: To prevent damage, the following procedure must be used when removing an Anode Lead from the Flyback Transformer.
1) Push the Anode Lead down.
2) While holding the lead down rotate the lead 90º counter clockwise.
3) Carefully remove the Anode Lead from the Flyback Transformer.
CRT REPLACEMENT
1. Removal of the CRT
Caution! High voltage should be completely discharged prior to CRT removal. Since the CRTs receive high voltage from the Flyback transformer, discharge the CRTs by shorting the open end of the respective high voltage cable to chassis ground.
1. Refer to Cabinet Disassembly and remove the Light Box Assembly. 2. Remove the three Anode Lead Wires from the Flyback transformer and discharge the CRTs. (Use the above procedure) 3. Unplug the three PCB-CRTs. 4. Remove 4 screws "a" retaining the Optical Unit. [Figure 1] 5. Remove 4 screws "b" retaining the Lens of the respective CRT 6. Lift the Optical Unit from the Light Box and set it lens down on a flat surface. 7. Remove 4 screws "c" retaining the CRT. [Figure 2] Note: DO NOT loosen the spring loaded screws. Doing so will break the seal between the C-Element and the # 6 Lens, causing leakage of the CRT Coolant. 8. Remove the Deflection Yoke from the neck of the CRT. [Figure 3]
