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.

Complete manual including mechanical part in good pdf quality. Shaded greys of the pcb due to pdf not perfect but usable.

Nice pdf file of the manual sent promptly. Thanks.
For fast insertion on RIN, GIN, BIN inputs then brightness, contrast and white point RGB is possible
RGB output illustration during OSD mode During OSD, the DC level on RGB outputs is 200mV less then DC level on RGB outputs during black current measurement (contrast, brightness and white point RGB are inactive) � Blue stretcher The Blue stretcher can be divided into two stretch-frunction - the Standard blue stretcher - the Extended blue stretcher The blue stretcher reduces the R- and G- signals by 14% whenever the video signal exceeds a threshold level of 80%. The extended blue stretch With the extended blue stretch the reduction of the G-signal is 8% and for the R-signal it is 22% whenever the signal exceeds the threshold level of 80% When adjusting the white point be sure that the blue stetcher is inactive. In principal all features should be switched off during white point adjustments. � RGB output stages. Looking at the RGB output signals several DC-levels can be seen. The DC-levels of the H- and V-blanking are 0.5V below nominal black level of the video signal. At the end of the vertical blanking (line 19, 20, 21) the measuring pulses for Continuous Cathode (CCC)loop or two point black current stabilisation can be observed. These measuring pulses have three DC-levels: - A DC-level of-0.1V with respect to nominal black level during the leakage measurement (LO). This level is chosen so that it lies close to the black level in order to have an accurate measurement close to cut off voltage of the picture tube - A pulse of +0.25V with respect to nominal black level, which corresponds with a cathode current of 8µA - A pulse of 0.38V above nominal black level which corresponds with a cathode current of 20µA The pulse-levels of +0.25V and +0.38V can only be seen measured on alternating fields. The RGB blanking level tracks with the DC level of the black current measurement pulses. The RGB output stages supply the buffered RGB signals to pins 21, 20 and 19 respectively.
