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 This repair book is obsolete because the product I bout it for is pretty old.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
Excellent manual including schematics. The service was great and the manual helped complete the job.
