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.

IF Demodulator and Video Chroma
Demodulated video signal is output from pin 10 going to sound traps. There are two sound traps, TR100 for I/L signal and TR101 for BG, outputs from which are switched by SOUND-SWITCH from IC301 pin 5. After group delay correction at pin 13, it is connected to pin 14 where TV picture is supplied into video switch. The TV signal from pin13 is also connected to SCART1 as TV signal output. Quasi Split Sound converted from SIF input is output at pin 5 to connect with sound decoder IC301. H and V sync pulses are output at pin 60 and 61 to go to FC/MSC for Synchronisation to convert progressive scan. H pulse must be inverted by Q126. When selecting one of video signal in video switch of IC100, CVBS signal is going to COMB filter if the video is CVBS PAL/NTSC format. Then Y/C separated signal is coming back at pin 28 and 29. The clock must be provided from pin 30. The video or Y/C signal selected pass through video chroma section and finally converted to YUV format at pin 49, 50, 51. IC100 is supplied 4.43MHz and 3.58MHz clock from crystal X100 and X101, which is automatically selected according to the signal received. 2 RGB inputs are also switched at the last stage in IC100. RGB signals are also converted to YUV. Video Switch.
