Even if the PDF is a scan, I can read the information I need.
The price is affordable and the service (mail sending) is very fast.
Thanks ! Regards. William (Fan of Kenwood)

Very good quality original datasheet!I like this amazing website!!!!!!
 ;
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.
SERVICE MODE
7. THE METHOD TO INITIALIZE THE VIDEO DATA
1. 2. 3. 4. 5. 6. 7. 8. When [484] is sequentially pressed in MENU mode, the SERVICE mode is activated. Choose � CHANGE OF VIDEO DATA�by pressing [3]. The input video signal should be PAL or null signal and the speed should be SP. Change A1 bytes to all � by the [ 1� ],[ ], [OK] buttons. The data are stored in EEPROM when [0] button is pressed. Pull out the mains power cord. Instantly short the both leads of C524 on MAIN PCB to reset the VCR. Plug in the mains power cord again.
8. THE METHOD TO CONTROL THE SERIAL DATA
1. Access to the SERVICE MODE by pressing [484] buttons sequentially in MAIN MENU. 2. Choose � CHANGE OF VIDEO DATA� by pressing [3]. 3. Then the data table which indicates the current video system (PAL/SECAM) and speed (SP/LP) is displayed on screen, while it detects the system and speed automatically. 4. Select the system and speed using [PAL/SECAM] button and [SP/LP] button on remote control if you need to change. 5. The cursor on the data table moves from right to left when the [ ] button is pressed. 6. The cursor on the data table moves from up to down when the [ ] button is pressed. 7. Data is toggled whenever the [OK] button is pressed on the cursor position. 8. If you need to change the data related to TRICK PLAY, it can be easily accessed in STILL mode. 9. First, the mode of the system detection should be AUTO mode after you change the data, and then if [0] button is pressed after this, the data of the current status are stored in EEPROM, then the SERVICE MODE MENU is displayed. 10. The data corresponding to the system, speed, input selection, trick play are not changed. * The group indication part on the data table is changed as in order of A1, A2, � P1, P2, � M1, M2, � S1, S2, � (SECAM ONLY) A1, A2, � whenever the [PAL/SECAM] button on remote control is pressed, the system detection of which are A(AUTO), P(FORCED PAL), M(FORCED MESECAM), S(FROCED SECAM) respectively. * The data changed to the current system according to the input video signal automatically in case of AUTO mode and if no signal, it changes to PAL system. * Adjust the correct system by pressing the [PAL/SECAM] button on remote control if the current status of the system is not correspond to the input video signal.
