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.

1. SAFETY INFORMATION
1.3 CHARGED SECTION, HIGH VOLTAGE GENERATING POINT AND X-RAY PROTECTION
7 Charged section
The circuit in which the commercial AC power is used as it is without passing through the power supply transformer. If the charged section is touched, there is a risk of electric shock. In addition, the measuring equipment can be damaged if it is connected to the GND of the charged section and the GND of the non-charged section while connecting the set directly to the commercial AC power supply. In this case, be sure to connect the set via an insulated transformer and supply the current.
7 High voltage generating point
The place where voltage is 100V is generated. 1.Charged seciton DEFLECTION assy (including FBT) (30.5kV, 1.2kV, 210V,135V) 2. POWER SUPPLY assy (135V) 3. R. CRT DRIVE assy (10.5kV, 210V) 4. G. CRT DRIVE assy (10.5kV, 210V) 5. B. CRT DRIVE assy (10.5kV, 210V) 6. CRT assy R (CRT service assy R) (30.5kV) 7. CRT assy G (CRT service assy G) (30.5kV) 8. CRT assy B (CRT service assy B) (30.5kV) 9. Focus variable resistor(VR1) (10.5kV) 10. Deflection yokes (L1, L2 and L3) Approx. (1100V at peak)
7 Charged section (Power supply primary side)
1. The primary side of the AC IN assy 2. AC power cord 3. The primary side of the POWER SUPPLY assy 4. AC power cord for DTV STB (PRO-710HD, PRO-610HD and PRO-510HD Only) : Part is the charged section. : Part is the high voltage generating points other than the charged section.
7 X-ray protection
Regarding the parts which are relative to radiation of Xrays (There is the danger to radiate X-ray from the individual CRT assy R, G, B), there are notifications of caution in the individual schematic diagrams. Be sure to read them for safety�s sake. The component parts for X-ray protection are as follows : When the current flows to the CRT assy R, G, B, be sure to perform it with these parts being attached. Protection from the X-ray radiation is maintained in the state in which these parts have been installed to the CRT assy. R, G, B. Accordingly, never supply current only to the CRT assy R, G, B. Moreover, the anode voltage of the CRT assy R, G, B should always be kept not higher than the predetermined value (in the minimum brightness and picture state when non signal input is less than 30.5kV). Be sure to drive the CRT assy R, G, B by using a completely functional DEFLECTION assy which have been adjusted completely in the combined state. (When the voltage abnormally becomes high, the X-ray protection circuit will operate.) 1. CRT assy R, G, B (Do not dismantle CRT assemblies under any circumastances) 2. Each Lens assy
