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.).
DESCRIPTION OF BLOCK DIAGRAM
1. Video Controller Part & Display Data Transmitter Part.(MST9151) This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to the digital video signal using a pixel clock. The pixel clock for each mode is generated by the PLL. The range of the pixel clock is from 25MHz to 135MHz. This part consists of the Scaler. The Scaler gets the video signal converted analog to digital, interpolates input to 1280 x 1024 resolution signal and outputs 8-bit R, G, B signal to transmitter. Especially pre-amp / ADC / Video controller/ Transmitter are merged to one chip"MST9151" by MSTAR. This part transmit digital signal from the Scaler to the receiver of module. 2. Micom Part This Part consists of EEPROM IC which stores control data, Reset IC and the Micom. The Micom distinguishes polarity and frequency of the H/V Sync are supplied from signal cable. The controlled data of each modes is stored in EEPROM. 3. Power Part This part consists of the one 3.3V and one 2.5 regulators to convert power which is provided 5V in LIPS Board. 5V is provided for LCD Panel. Also, 5V is converted 3.3V and 2.5V by regulator. Converted power is provided for IC in the main board. 4. Inverter The inverter converts from DC12V to AC 700Vrms and operates back-light lamps of module.
