 KA-87 KENWOOD Service Manual by Andrew Krystiniak;
Payments were processed quickly and items were exactly as described. I will use in the future for any other manual needs.
 ST-610 TECHNICS Service Manual by Ian Hill;
The Technics manual was very clear and I was able to solve my technical problems. I did not think that anyone kept these manuals and was pleasantly surprised to find them on the Internet and at an affordable price. I would recommend Owner Manuals as a first source of technical products for β€˜dated’ equipment manuals. Ian
 CS4125 KENWOOD Service Manual by Randall Hurd;
The content of the manual was not found on the Internet and was a hard find. I check the net for 5 hours until I came across this web-site. When I did find the book it Auto loaded into my IPAD PDF shelf for books for review at anytime. Overall I am satisfied with the book and it answered all my questions. This repair book is obsolete because the product I bout it for is pretty old. Thanks for the help with the download and even having the manual. Thanks 73's K5HRD

It was magic after so many years to still be able to source this info. It was equally amazing to return my Pioneer receiver to it near new sound quality AFTER NEARLY 30 YEARS! Thank you for this ability!
