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 This repair book is obsolete because the product I bout it for is pretty old.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

Easy and secure way to get a complete service manual of a vintage hifi component. Only some parts of the print copy are dificult to read. Nice price!
