Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!
Very good quality scan of the document. I am very pleased with what I got.
