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.).
s) Ribbon code sensor/luminance quantity adjustment (CN5-3, 19) Function : This is a transmission type sensor that reads ribbon code and starting mark on the ink ribbon. Pair LED luminance is set to obtain the most suitable luminance quantity. When reading ribbon code every time, the threshold level value for judging L or H is changed to the most suitable value. Level : Ribbon code portion is H, others are L Check method : Make sure the threshold level, ribbon cassette should be inserted, ribbon should be rotated correctly, make sure the sensor output. t) OHP sensor/luminance quantity adjustment (CN5-15, 21) Function : This is a transmission type sensor that detects paper kind after feeding paper. Pair LED luminance is set to obtain the most suitable luminance quantity. When reading ribbon code every time, the threshold level value for judging L or H is changed to the most suitable value. Level : Ordinary paper is H, OHP is L. Check method : Make sure the threshold level, transmit the paper, and make sure sensor the output. u) Head thermistor (CN7-27) Function : This thermistor measures temperature of the thermal head. Level : Approximately 2.5V at the normal temperature (25�C) Check method : Measure the voltage of thermistor. v) Room thermistor (CN4-17) Function : This thermistor measures the temperature at the inside of the unit. Level : Approximately 2.5V at the normal temperature (25�C) Check method : Measure the voltage of thermistor.
