Manual was a good representation of service infomation for the EWV404. It worked well for my repair.
Great quality copy, right what I was looking for, all I need to fix my radio.
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.
