I found this service manual to be complete in every detail except for troubleshooting charts. It would be helpful if it had a set of troubleshooting charts; however it is a very good manual otherwise and for the price it is very well worth it.

Complete manual included schematics layouts and alignment procedure, clear to read and magnify, extremely pleased with manual and owner manual . com's service
