This is the original manufacturers service manual, with detailed info on the circit boards, explosion drawings of all parts in assembly order, and tuning instructions. The only thing missing is the information on the dimensions of the various drive belts. mail me if you need them. gcrossman_at_aol.com

Ordered service manuel for a hard to find plasma tv - your company made it easy to find and purchase - I will use you again
Thanks for your help
 ;
This is a high quality manual with clear schematic and components layout diagrams ; with service procedure included.
;
This service manual for the Kenwood KT-990D was reproduced really well ,is very legible and manual is complete.Combined with the low price paid,in the future,I will be checking Owner-Manuals.com any time I need a manual.
;
When I purchased this manual I had my doubts regarding the quality as the price was so reasonable as compared to other outlets.
The manual itself is of high standard the print is very clear as are the diagrams. Obviously with the diagrams one has to zoom in otherwise it is to small to be able to read.
Overall I am very pleased with the company who delivered as they said and with the manual they supplied.
I occasionally require a manual and now having registered with this company I shall order from them in the future.

Turn on the oscilloscope graticule to full brilliance and either reduce room lighting o r place a black cloth over both your head and the camera. Adjust the oscilloscope brilliance until the trace can be easily seen on the frosted plate. NOTE
1) Due to the separation between the graticule and the oscilloscope phosphor, the square wave will now appear shorter horizontally than the graticule. This is caused by parallax (paragraph 5-5).
2) Note that the graticule will not be in focus. This is because of the poor depth of focus
j.
should be exactly 1 cm apart. I they are closer tof gether than that, more lens gaskets must be added to correct the ratio. I the lines are wider than that, f then one or more gaskets will have to be removed. In either case, steps a through k will have to be repeated until the desired ratio has been attained. n. Working through the lens access door and using
the stubby screwdriver, loosen the lens mounting
screws just enough to allow a hindered movement of
the lens- jamnut assembly. p. Move the lens until the center of the graticule lines up with the cross hairs on the plexiglass plate.
with the large lens opening (paragraph 5-8). This will have no effect on the accuracy of the following adjustment. k. Since, due to parallax, the oscilloscope presentation and the graticule as seen on theplexiglass plate will be a different horizontal size, you will have to decide whether you want the graticule o r the oscilloscope presentation to be a perfect 1-to -1 ratio. m. Measure the desired presentation with a centimeter scale. I a 1-to-1 ratio is desired, the lines f 6-4
q. Tighten the lens mounting screw evenly, working around the lens several times. 6-16. REFOCUSING. 6-17. GENERAL. The 196A Oscilloscope Camera is prefocused at the factory on a plane 3/8 inch from the camera nose, which is the standard combined thickness of the graticule, filter and cathode ray tube glass. Unless the camera has been dropped, o r a non-standard lens-to-object distance is desired, the camera should never need refocusing. An alternate 01038- 1
