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.).

After issuing the focus close command, the following processes are taken for both DVD and CD. 1. Measure and optimize signal levels First drive PU lens far from the disc and then drive closer to the disc. At the focal point met in the process of this move, measure signal levels of FE, AS and RFENV respectively, and optimize their levels for FE and AS (1 & 2 in the above figure). 2. Focus closing Next, drive the lens far from the disc again to detect the closing levels of FE and AS. Then activate focus loop filter for closing focus (3 6). 3. Check closing Check the closing with signal levels of AS and RFENV (6 & 7). Focus search in test mode can check the signal levels and focus drive voltages for FE, AS and RFEV.

1.2.2 Tracking Close
After issuing the tracking close command, the following processes are taken for both DVD and CD 1. Tracking brake Measure one half cycle of the tracking cross and if the cycle is within the range of designation, output the brake pals. Output direction of brake pals is determined by the phase relations of OFTR and TKC (TE's binarization) signals. After confirming that the swing of lens against disc is controlled, the brake stops and the closing begins. If the closing condition is not met within 10msec. after outputting brake, the brake stops and the closing begins. 2. Tracking closing Process the tracking drive hold with OFTR signal. 3. Check closing Check whether or not the track jump does not exceed the designated number within the designated term. Closing check will be time-out at 20msec. Retry using a command from the microcomputer.

1.2.3 Track Jump
The system selects from three types of methods; i.e. interval jump, multi jump and traverse seek, according to the target number of moving tracks. 1. Interval Jump The detailed seek is capable due to the execution of repetitive one-track jumps. It is used when approaching to the target track or seek-operating to an adjacent track. 2. Multi Jump It counts both edges of the track cross signal TKC and moves for designated number of track counts. 3. Traverse Seek It controls the movement speed by measuring the time of the track cross signal TKC and manages the vibration of pickup generated upon movement to the minimum. Types of target number of moving jumps illustrating the jump switch setting for both DVD and CD DVD 1-10 Interval Jump 11-100 Multi Jump 101-500 Combination of Multi Jump and Interval Jump Over 501 Traverse Seek The waveforms of track jumps are shown in the next page.
