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
;
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.
2) Transmitter
1. Microphone Amplifier
The microphone amplifier IC301 has 2 operational amplifiers. The voice is converted into the electric signal through the microphone, and then supplied to IC301. The input signal is amplified and pre-emphasized to be output. [VHF] The signal output from microphone amplifier is adjusted the maximum frequency deviation at VR2. The adjusted signal is added to the cathode of VCO variable-capacitor D4 for deviation to change the capacity of the oscillation circuit resulting the FM deviation. [UHF] The signal output from microphone amplifier is adjusted the maximum frequency deviation at VR1. The adjusted signal is added to the cathode of VCO variable-capacitor D10 for deviation to change the capacity of the oscillation circuit resulting the FM deviation.
2. Power Amplifier
The oscillated signal at VCO is supplied to the power amplifier Q3, passing through buffer amplifier Q5, driver amplifier IC1. The power-amplified signal is supplied to the antenna through the duplexer after the harmonics are attenuated enough.
