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.).
 ;
The Service Manual for the Kenwood KR-V55R provided by owner-manuals.com was as described/advertised. The contents provided the necessary information to effect a diagnosis of the unit. The schematics above all else was instrumental in tracing the the signal flow from component to component.
 ;
This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.
CIRCUIT OPERATIONAL DESCRIPTION
4) SDRAM : HY57V660ET-7 (DV-000S/DV-00S/DV-200S/DV-300S/DV-400S/DV-70S) This sends and receives data with MPEG decoder and performs the video signal processing. Every video signal output from DVD player is once stored in SDRAM and then encoded in MPEG decoder and finally output into the analog signal. SDRAM applied to DVD module has the capacity of 6MBit(048576 x 6bit x Bank), sends and receives data with MPEG decoder by 6 bit. Description THE Hynix HY57V660E is a 6,777,26 bits CMOS Synchronous DRAM, ideally suited for the main memory and graphic appli-cations which require large memory density and high bandwidth. HY57V660E is organized as 2banks of 524,288x6. HY57V660E is offering fully synchronous operation referenced to a positive edge clock. All inputs and outputs are synchronizedwith the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth. All input and outputvoltage levels are compatible with LVTTL. Programmable options include the length of pipeline (Read latency of ,2 or 3), the number of consecutive read or write cycles initi-ated by a single control command (Burst length of ,2,4,8 or full page), and the burst count sequence(sequential or interleave). Aburst of read or write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by anew burst read or write command on any cycle. (This pipeline design is not restricted by a `2N` rule.)
