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!
No. Adjusting point 1 115V adjustment: R711 Adjusting procedure/conditions 1. Receive the Monoscope Pattern signal. 2. Set to the P-NORM mode. 3. Connect a DC milliammeter between TP602(â) and TP603(+). 4. Take the beam ammeter reading to make sure that the beam current is between 900 ÂµA and 1100 ÂµA. * If not, readjust the FBT screen control to obtain the beam current of 900-1100 ÂµA. 5. Connect a digital voltmeter to TP701. 6. Adjust R711 so that the digital voltmeter should read 115 Â±0.5 V. Waveform and others No. Adjusting point 1 VCO adjustment: T203
Adjusting procedure/conditions 1. Disconnect the antenna from the tuner antenna terminal. 2. Apply DC voltage to pin (4) of IC201 (IF AGC). Â» DC voltage: 6.0 V (allowable +0.1 V) 3. Using a digital voltmeter, measure the DC voltage at pin (20)(PLL FIL) of IC201. * The digital voltmeter must be able to take readings down to the third decimal place. 4. Relieve pin (4) of IC201 of the DC voltage. 5. Reconnect the antenna in position and receive the E-12CH signal. (With the AFT off, adjust the receiving frequency to 224.25 MHz.) 6. Connect the DC digital voltmeter to pin (20) of IC201. Adjust T203 so that the voltmeter should read the same voltage as in Step 3. Allowable error : 0.015 V (20 kHz) 1. Receive the PAL Colour Bar signal. If this signal is not available, any signal above the E-5CH band is acceptable. Â» Field strength : 55-80 dBÂµV Make sure the frequency is almost the same as that of the received channel (Â±30 kHz). 2. Using the channel setting control, make a frequency of 224.25 MHz appear on the screen (the AFT turns off). If any other channel than Colour Bar is received, make its frequency on the screen. (The AFT turns off when the on-screen display turns yellow.) 3. Turn T204 clockwise to have a 6V point, and counterclockwise to have a 0.2V point. Position the coil at the center of these two points. 4. Adjust T204 so that the DC voltage at pin (1) (AFT OUT terminal) of IC201 be 3.3 Â±0.1 V. (See Fig. 3) 1. Receive the PAL Colour Bar signal. Â» Field strength : 57 Â±1 dBÂµV (75 ohms open) 2. Connect the oscilloscope to TP210, as shown in Fig. 4. Oscilloscope TV Set + TP210 0.1V â Bias box
Waveform and others * Warm up the unit for longer than 10 minutes in advance.
* 10 kHz at about 0.007 V.
* Position the T203 core in the range in which the Colour Bar signal can be received.

No. Adjusting point 1 Tuner IFT (preset): TU201 Adjusting procedure/conditions 1. Get the tuner ready to receive the E-9CH signal. but with no signal input. Adjust the PLL data. 2. Connect the sweep generatorâs output cable to the tuner antenna. (RF sweep) 3. Adjust the sweep generatorâs output level to 80 dBÂµV. 4. Connect the response lead (use a low-impedance probe with wave detector; see Fig. 1) to the tunerâs IF output terminal. (This terminal must have the probe alone connected.) 5. Set the RF AGC voltage to 0-6 V with no contact with the waveform. 6. Adjust the tuner IF coil to obtain the waveform as Fig. 2. shown in Note: Be sure to keep the tuner cover in position during this adjustment. Waveform and others

Fig. 4 Â» Bias box: About 4.5 V 3. Turn R216 to have the highest voltage. 4. Turn R216 slowly in the opposite direction until the voltage goes down 0.1 V below the highest level. 5. Adjust the signal level to 63-67 dBÂµV and make sure there is no noise. 6. Now adjust the signal level to 90-95 dBÂµV and make sure there is no chrominance modulation beat.
