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 ‘dated’ equipment manuals.

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 This repair book is obsolete because the product I bout it for is pretty old.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
