This is a good quality scan of the service manual which includes an assembly diagram, block diagram, schematic, and parts list. Exactly what is needed to repair my KR-V55R receiver.
;
Excellent concise manual. All needed information was included. Typeface and diagrams were clear. Very fair price considering what others are charging. Many thanks

Response is a little slow- I had to wait 12 hours to receive download link but it says that it may take up to 24hrs.
Manual is old and was not produced in PDF- scanned copy is exellent.
Overall- value for money- I recommend

Excellent quality and quickly delivered manuals at a fair price. Great care is taken in the reproduction process. Even photographs and highly detailed drawings are as clear as in the original. That cannot be said for some freelance manual copies I have obtained from the web. If you have exhausted your internet search of technical manuals, try Owner-Manuals.com. If they do not have it, I do not think it exists. Perhaps, if requested, they may be able to find it. Their resources are certainly greater than most. Shopping here certainly beats waiting for months or years for the manual you seek to appear in an internet auction or garage sale.

Very detailed product, also it is a scanning from original, very useful if you have to service this type of amplifier ! Very good product, very hard to find!
SECTION 6 ELECTRICAL ADJUSTMENTS
Note: 1. Perform adjustments as given. 2. Power supply voltage: DC14.4 V (more than 3A).
� TRACKING OFFSET CHECK � RF BOARD (Conductor Side) �
oscilloscope CNJ12 + � BP11 (TE) TP (VC)
� FOCUS GAIN ADJUSTMENT (COARSE ADJUSTMENT) This adjustment is to be performed when replacing the following parts. � Optical Pick-up Block � RV14 � RF BOARD (Conductor Side) �
CNJ12
� When gain is lowered... The set does not play because of no focus operation. � When gain is highered... Operation noise is heard due to a scratch or a dust, then operation will be unstable.

TP (VC) IC11
Procedure: 1. Connect the oscilloscope to BP11 (TE) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc. 3. Press the . AMS > button, and check the traverse waveform*. 4. Confirm that the oscilloscope waveform is symmetrical on the top and bottom in relation to 0 V dc, and check this level.
* Traverse waveform: This is the tracking error wave form appears when crossing the track.

Procedure: 1. Connect the oscilloscope to TP (RF) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc. 3. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not.
Note: Clear RF signal waveform means that the shape ��� can be clearly distinguished at the center of the waveform.
Procedure: 1. Set RV14 (RF board) to the standard position. 2. Check that there is not an abnormal amount of operation noise (white noise) from the 2-axis devise. If there is, turn RV14 slightly clockwise. � RF BOARD (Conductor Side) �
