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!

VOLT/DIV : 0.2V TIME/DIV : 2mS
VOLT/DIV : 0.2V TIME/DIV : 2mS
VOLT/DIV : 0.2V TIME/DIV : 2mS
4-3-3 To Adjust Focus Gain (PLAY mode)
1. 2. 3. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to AP1. Load and play the disc While the disc is running adjust the gain with WVR2 as shown in the following figure. Normal frequency Low frequency High frequency
---250mV ---100mV ---0 V ---0 V ---100mV ---0V
VOLT/DIV : 0.1V TIME/DIV : 2mS

4-3-4 To Adjust E/F Balance (PLAY mode)
1. 2. 3. Set TIME/DIV of the oscilloscope to 2mS. Set Volt/DIV of the oscilloscope to 0.5V. Ground the scope input and set to DC and then set the DC range. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to center to AP2. Load and play the disc. Turn WVR1 counterclockwise to the minimum value. Raise WVR3 and adjust the waveform so that its middle comes to GND of the oscilloscope (or until the upper half of waveform becomes symmetrical to the bottom half, A=B) Adjust WVR1 (arrow) for normal sound.
4-3-1 To Adjust FOCUS BIAS(STOP mode)
1. 2. 3. 4. Set Volt/Div of the oscilloscope to DC 100mV. Ground the scope input and set the waveform to 0V, DC range. Connect the GND terminal of the oscilloscope to Vref, and (+) terminal to center of AP1. Set WVR4 to 0mV.
