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.

4. Confirmation of the RF level
Test point: RF and VC (Vref) Test disc: TCD-782 Confirm that the RF waveform appears as shown below.
At 0.8 Vp-p or greater
VOLT/DIV: 200mV TIME/DIV: 0.5us
5. Confirmation of tracking balance
Test point: TE and VC (Vref) Test disc: TCD-782 Press the DSL button while the test disc is playing and confirm that the traverse waveform is as is shown below.
VC
VOLT/DIV: 200mv TIME/DIV: 2ms
6. Confirmation of each servo
It is possible to confirm the adjustment value of each servo by repeatedly pressing the MODE button while the test disc is playing. The switchover sequence is as stated below. Confirmation mode OFF -> Focus bias (FB) -> Tracking balance (TB) -> Tracking gain (TG) -> Tracking error offset (TEO) -> Focus gain (FG) -> Focus error offset (FEO) -> Confirmation mode OFF Example: Tracking error offset (TEO) Adjustment value-> 03
Tracking error offset (TEO) display
