This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

thank u so much for this manual that was so cheap that i thought it was a scam but i gambled anyway because it was too good of a deal to pass up and behold,the manual has everything and details of everything even the screws and im still amazed and very happy with my manual .so take my word and jump on it before they realize how cheap they selling thier manuals..thank you so much for taking time to read my thoughts

I do not have very much to say.
The price is quite covenient, delivery was better as promised (about 12 ours, against the specified 24 hours if I remember well), and the quality of the PDF is more than acceptable.
The Service Manual of Sansui R30 itself is also satisfactory: good graphic for schematics and layouts, simple and well structured.

Happy to find finally a schematic for this amplifier. The schematic is of good quality, the pcb layout is useless: all is black. Never the less, it is very easy to find the components on the board using the schematics.

Hard to find manual was ready the next day. Scans were very legible (including schematics). All the essential parts of the service manual were present (adjustment procedure, schematics, and parts list). It would have been nice if the rest of the manual was included (disassembly procedure, theory of operation, etc.).

4. Fusing section
After transfer, toner on the paper is heated and fused in the fusing section. This machine employs the heat roller pressure pad system for fusing.
Heat roller:
This roller is made of aluminum tube (14mm diameter and 0.5mm thickness) coated with teflon which has a high friction coefficient (for greater transport force) and a high separation capacity. The 400W halogen lamp is used. This spring presses the heat roller with a 690g pressure on one side. The pressure pad is covered with the teflon sheet for smooth paper transport when fusing. The employment of the pressure pad and the teflon sheet allows fusing in a low pressure (only 690g on one side). Two thermistors of chip type with good response are used to respond to rapid heating (rapid warm-up of about 8sec) of the heat roller. One is in close contact with the heat roller to detect the heat roller temperature. The other is separated from the heat roller to detect the ambient temperature.

Thermistor:
Temperature fuse 1: Temperature fuse 1 is installed to the fusing cover. It blows off when the ambient temperature of the fusing cover rises abnormally (132�C). Temperature fuse 2: Temperature fuse 2 is in close contact with the heat roller. It blows off when the heat roller temperature rises abnormally high (187�C).

B. Operations
This machine uses two thermistors; one is in close contact with the heat roller to detect the heat roller temperature (Thermistor 1 in Fig. 12-24), the other is separated from the heat roller to detect the ambient temperature (Thermistor 2 in Fig. 12-24). The heat roller temperature is controlled by these both data. (Temperature control is performed by turning on/off the heater lamp.) For example, the heat roller temperature is controlled to 155�C when the ambient temperature is 25�C. When the ambient temperature falls, the heat roller temperature is raised. When the ambient temperature rises, the heat roller temperature is lowered.
