Great manual, great price. Has a few of the basic operating instructions that most service manuals leave out. Complete instructions for disassembling board by board, safety precautions, schematics, complete parts list.

Thank You !
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.
