Hi Ki,
When I purchased my 1510A last year, I received a PDF copy of the service manual, as well as a complete printed copy. I'll be traveling tomorrow but will arrange to put a copy up on my iDisk for you later this weekend (the file is about 72 MB). As I recall, the quality of the PDF scans isn't great, but if there is something that needs clarification, I can scan specific pages at high resolution for you later in the month. My printed copy is very complete, with later revisions, service bulletins, etc. It's absolutely massive ? larger than the service manual for the Sony APR-5000!
