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

Controlling (automatic) the Fluorescent Lamp Intensity (ALVC control)
Outline When pre-activation pre-heating is over, the microprocessor (QlOl) on the DC controller PCB instructs the microprocessor (Q501) on the composite power supply PCB to generate the scanning lamp on signal (FLAON*). At this time, the fluorescent lamp driver circuit operates to apply the output of the primary side of the main transformer (T102) to both ends of the scanning lamp so as to turn on the scanning lamp at a high frequency. Controlling the Intensity of the Scanning Lamp a. Outline The intensity of the scanning lamp is controlled by the microprocessor (Q501) on the composite power supply PCB. The intensity sensor checks the intensity of the scanning lamp and generates activation power to suit the intensity. The microprocessor, on the other hand, finds out the intensity of the scanning lamp based on the activation power to send the scanning lamp on signal (FLON*) to the on control circuit. Intensity Lower Than the Specified Value The microprocessor increases the duty ratio of the scanning lamp on signal (FLON*) sent to the fluorescent lamp driver. The fluorescent lamp driver, in turn, increases the current flowing to the scanning lamp, thereby increasing the intensity of the scanning lamp. Intensity Higher Than the Specified Value The microprocessor decreases the duty ratio of the scanning lamp on signal (FLON*) sent to the fluorescent lamp driver. The fluorescent lamp driver, in turn, decreases the current flowing to the scanning lamp, thereby decreasing the intensity of the scanning lamp. c. b. 4.

The ,copier executes ALVC control in which the ON voltage of the scanning lamp is automatitally corrected to prevent changes in the copy images caused by deterioration of the photosensitive drum.
