Perfect quality. Was able to fix speed drifting on my Sansui Turntable using the service manual instructions for PLL adjustment.

I am very happy regarding the online purchase of this manual from Owner-Manuals.com as with this I could set right my Denon CD player and Amplifier.
I once again sincerely thank them for the prompt service which was rendered to me.

More than pleased with my prurchase, very good product for the price.

Manual-link came 30 minutes after having paid for an extremely rare (40 years old) item (sony icr-120) and helped me to get the radio rework again. So really good help for me, fast and reliable delivery and -taken that into consideration- a very reasonable price for that service. So thanks again! Mike, Germany

Some of the pictures in this manual are a bit irritating. I had to dissassemble the unit and some of the screws have different threads, which is not mentioned in this manual. Also some of the drawings of the boards look different than the actual boards.
After all, the manual was very useful. I was able to recalibrate the capstan drive and it is working fine again.

Staple motor (FFSM) drive circuit
Staple motor (FFSM)
This circuit controls rotation/stop and the rotating direction of the staple motor (FFSM), and is composed of the CPU (IC10) and the FET (Q10, 11, 12, 13). The DC motor is controlled with the staple motor (FFSM) drive normal rotation signal, the reverse rotation signal, and the brake signal outputted from the CPU (IC10-5, 8, 9pin). To protect the motor and the mechanism, the current limit circuit is provided, which supplies the motor drive OFF signal when the current flowing through the detection resistors R78 and R79 exceeds 3.8A, restricting the current not to exceed 3.8A. 8) Tray motor (FTLM) drive circuit 9) Fan (FFAN) drive circuit
Tray motor (FTLM)
Fan (FFAN)
This circuit controls the tray motor (FTLM) rotation, stop, and rotating direction, and is composed of the CPU (IC10) and the DC motor driver IC (IC19). The CPU (IC10-69, 70pin) outputs the tray motor (FTLM) drive normal rotation signal, the reverse rotation signal, and the brake signal to control the DC motor. In addition, the current limiting circuit is formed with R129, R130, R131, and R132 for the current flowing through the motor not to exceed 0.65A.
This circuit controls the fan (FFAN) rotation, stop, and rotating direction, and is composed of the CPU (IC10) and the digital transistors (Q14, Q18). The DA converter (IC11-13pin) outputs the fan (FFAN) drive signal to drive the motor. The fan lock signal is inputted through the noise filter of R168 and C130 to the CPU (IC10-20pin) by the open drain output of the fan built-in circuit. The logic of the signal inputted to the CPU is H when locked.
