Great quality copy, right what I was looking for, all I need to fix my radio.
Thanks

I BOUGHT A PAIR OF INFINITY VINTAGE SPEAKERS THAT REQUIRED TO BE REPAIRED AND THE ELECTRONIC TECHNICIAN ASKED ME FOR THE SERVICE MANUAL.
I TRIED TO GET IT AT THE MANUFACTURER'S SITE WITH NO SUCCESS, SO I STARTED TO LOOK FOR IT IN THE WEB FOR A LONG TIME, UNTIL I FOUND THE SERVICE MANUAL IN THIS EXCELLENT SITE "OWNER'S MANUAL.COM".
NOW I HAVE MY SPEAKERS WORKING AND ENJOYING THE MUSIC I LIKE.
THANKS TO "OWNER`S MANUAL.COM" I RECOMMEND THIS SITE TO EVERYONE.

Very quick response. Very good and accurate print quality of the scanned document.

The service manual was very usable and clear enough to see the individual values of all of the components (unlike some of the service manuals I have gotten in the past from web sites similar to this one). The price was right and the information was greatly appreciated. It helped me with an otherwise very difficult repair. It was much needed and appreciated. A faster turn around on my order would be nice, but I understand the constraints on your staff's time. Thank you for your service.

Excellent manual. Helped me out with disassembling and troubleshooting my projector.
4-7. CONTROL circuits
(1) HORIZONTAL / VERTICAL OSCILLATION circuit The sync signal input to IC301 is phase-sifted and converted to the waveform in IC301. The pulse synchronized with the horizontal sync signal is output from pin 17 as horizontal drive pulse. The sawtooth wave synchronized with the vertical sync signal is output from pin 4. The pulse output from pin 17 generates a frequency locked to the input signal under the following conditions:
Q The horizontal sync signal is input to pin 26. R The vertical sync signal is input to pin 27. S The feedback pulse (AFC pulse) of the HORIZONTAL DEFLECTION OUTPUT circuit is input to pin 18.
IC301 is auto-sync system and adjusts the horizontal frequency automatically make the vertical sync signal input to pin 27 trigger. In case that the AFC pulse is not input, the output pulse from pin 17 is unlocked and the horizontal picture size changes with keeping it small.
IC301 pin 26: Horizontal sync signal input
IC301 pin 17: H-DRIVE pulse output
IC301 pin 18: AFC pulse input (Threshold level: approx. 2V)
Center voltage: 3.5V
IC301 pin 4: V-sawtooth wave output
