Very helpfull information and I highly recommend this source for needed information about your products.
 ;
More than pleased with my prurchase, very good product for the price.
;
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
