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.
I am very pleased with the service manual for my RT-909. This was an easy purchase and great procuct, and much cheaper than other venues i had looked at. This web site is now listed in my favorites list. KEEP UP THE GOOD WORK. THANKS. J. BROWN
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.
