I had been looking for a Manual for my CS2150 for quite a while -- in fact I had just about given up. I saw this site and decided to download the Manual. When I Received it by Email I was really pleased with what I got, with the result that My Kenwood 'Scope is now 100% repaired and working well. As an AV Serviceman, you need a good 'scope, and thanks to this site, and the Service Manual, I have been able to repair it. The Manual was a copy of the Factory Original and the copy was very clear, especially in the area of the Circuit Schematics, where You really need to be sure of what You are looking at.

I recently purchased a manual for a Samsung DLP tv to help with a trouble shooting problem I was having. Every tv repair shop wanted close to $400.00 for the fix, but after I found Owner-Manuals.com I hit pay dirt. The manual they had for me to purchase and download was a complete service manual for the exact tv I needed. It was complete with wiring diagrams, schematics, and even part numbers. If your the fix it yourself type I highly recommend trying to find any manual here before paying someone else to fix whatever problem your having.

Once again, excellent price and manual delivered in a timely manner and as advertised!

T-7 top core
Adjust for stable scope display
1. Turn off 19KC pilot on MPX generator. 2. Adjust upper core of T-7 to obtain a stable and uniform 1 KC signal scope display. This adjustment may be critical, so turn core very slowly. 3. Turn 19KC pilot back on. Modulate left channel and measure right channel output. Adjust L-5 for minimum right channel output (maximum separation). Be sure all test leads are removed from TP#2 for separation tests. Modulate right channel and measure left channel output. Separation in steps 5 and 6 should be at least 30db.
L-5
30db separation or more SAME
This step checks the rejection of 19KC and 38KC frequencies. Residual output should be at least 40db below modulated output. MPX light adjust control R-12 Turn control until light comes on. Then back off just enough to cause the light to go off. Then back off about 1/8 of a turn more. Light should operate ONLY on a MPX signal.
