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.
;
Impeccable, document très complet. Perfect, i get all i need. All schematic are correct. Thanks
(7) Check first that indication �L� of �AC1L� on the LCD (Tuner [1]) has disappeared, and then press the S708 switch on the RF-92 board (WRU-806A, Tuner [1]). n If the �L� indication does not disappear from the LCD (on A area: refer to the previous procedure (5) (when the RF input level is lower than the reference level) or �H� is displayed (when the RF input level is higher than the reference level), perform the following adjustment. 1 Check the RF output level and frequency of the signal generator (perform re-setting if necessary), and repeat from procedure (1). 2 If the above conditions (the �L� indication does not disappear, or �H� is displayed) remain even after re-adjustment, it is necessary to check the WRU-806A Tuner Unit.
