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

C : panel designation. U : B+ Line. Power voltage is dc 3.6 V and fed with regulated dc power supply from external power voltage jack (CN301). Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : Talk Voltages are taken with a VOM (Input impedance 10 Mâ¦). Voltage variations may be noted due to normal production tolerances. Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.
