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!

B+,REM terminal
set Stabilized Power suppy GND terminal
Procedure : 1. Rotate the variable resistors RV105 and RV205 fully in the clockwise direction to minimize the idling current of the stabilized power supply. 2. The input signal is to be no signal. 3. Set the power voltage to +14.4 V, and turn the remote mode ON (Connect between the REM terminal and B+ terminal). 4. Adjust each of RV105 and RV205 so that the power current of the stabilized power supply is increased in steps of 500 mA for the XM-1502SX and in steps of 600 mA for the XM-1902GX.
