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.

4-5 . AGING MODE (� Perform as necessary) The aging can be performed to the set in the test mode. The aging can be continued by the set number of times or until an error occurs. In the aging, the following operations are repeated. Table turntDisc chuckingtDisc detecttServo ontAuto adjustmenttTOC readingtPlay of first track for 5 secondtPlay of last track for 5 secondtPlay of first track for 5 secondtDisc unchucking Setting Method: 1. After setting the test mode, rotate the [l AMS L] dial to select �94. SET AGING� and press the [l AMS L] dial to enter. 2. When �AGING TIMES� is displayed, rotate the [l AMS L] dial to set the number of aging times. (For the number of times, every 10 times can be set. Setting 0 (zero) eliminates the count limitation where the aging is repeated until an error occurs)
Note: Do not perform unmanned overnight aging.
4-6. SHIPPING MODE The repaired set must be initialized, and for this purpose the set should be set to the shipping mode. Setting Method: 1. After setting the test mode, rotate the [l AMS L] dial to select �8d Set Up Init� and press the [l AMS L] dial to enter. 2. �8D 000000000 00� will be displayed, and if the scroll starts in the left direction, the set initialization has completed 3. Press the [POWER] button to turn the power off.
Note: Take care not to leave the test disc in the set.
The following setups are established in the SHIPPING MODE 1. Initialization of EEPROM (IC903) � PLAY MODE ALL DISCS, CONTINUE � COMMAND MODE CD1 � LAYER SELECTSACD � M/2CH SELECT MULTI � DIGITAL FILTER STD � 2ch SPK MODE 2ch DIRECT � Mch SPK MODEMch DIRECT � Resetting the accumulated hours meter. 2. Chucking at the DISC1 position.
3. Press the [l AMS L] dial, and �AGING START� will be displayed instantaneously, then �DISC IN & JOG ON� will be displayed and the tray will come out automatically. 4. Place a disc (CD or the SACD SL disc) on the tray, and press the [l AMS L] dial to start the aging. 5. At the completion of aging by the set number of times, the tray will come out automatically and the check will stop. Typical time required for aging About 1 hour/100 times �AGING SUCCESS!� will be displayed if no error occurred in the aging, or the error will be displayed if an error occurred. (Refer to the following error list)
Error List An error occurring during the check in the aging mode of the test mode is displayed automatically (scroll display) immediately when the error occurred. < How to view the error history > 1. Select �95 DISP ERROR� with the [l AMS L] key, and press the [l AMS L] key once. 2. The error that has occurred lastly in the set and the signal status (H = 1, L = 0) at that time are displayed on the FL display by scrolling. (Types of the errors and the signal status that can be checked, are the same as the error display of the aging mode.) 3. Press the [l AMS L] key once again to show the error history repeatedly. 4. When the error history is displayed with scrolling once, the mode returns to the normal test mode.
