The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John

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!
Abgleich / Adjustment Procedures
GV 5000 �, GV 5300 �

Test equipment: Oscilloscope with 10:1 Test Probe, Frequency Counter, Colour Generator Service work after replacing the Family Board: � Adjustment 1. Frequency Deviation Sync Value, R3054 2. Chroma Writing Current, R3038 Preparation AV recording (do not feed in an signal). Frequency counter: ............................................ 1911-(2) Connect IC7051-(2) to +5V. Oscilloscope: ...................................................... 1911-(2) Feed in a PAL red raster test pattern with 75% saturation (ratio burst: chroma = 1 : 2.2). AV recording. Adjustment Procedure Set frequency counter with R3054 (Sync. Frequ.) to 3.8MHz
±10kHz.
Set Chroma signal with R3038 (CHROMINANCE WRITING CURRENT PAL) to 71mVPP (-12.5dB of the FM-signal). Disconnect IC7051-(2) from +5V.
2.4 Family Board � Standard Sound / Audio Linear (AL)
Test equipment / aids: AF Millivoltmeter, AF Generator, Video Cassette of reputable brand. Service work after replacing the Family Board or the RP-Head: Adjustment no. 1.1, 2 Adjustment 1. Erase Frequency 70kHz, F5603 1.1 Bias (70kHz), R3618 1.2 Frequency Response Test Preparation Frequency counter: ............................................. 1918-(7) Record AF millivoltmeter: ................................................... R3600 Record. � Connect IC7601-(10) via 270� resistor to ground. � Feed in a CCVS signal via EURO-AV socket, contact 20. � Feed an audio signal of 200mVrms (480mVPP) from the AF generator to the EURO-AV socket, contact 2 or 6. � Make a recording of 400Hz and 8kHz each of 1 min at least. Afterwards play back these recordings. � Connect an AF millivoltmeter (oscilloscope) to EURO-AV socket, contact 1 or 3. AF generator (1kHz / 0.7Vrms): ..................................... EURO-AV socket, contact 2 or 6 AF millivoltmeter: ......... EURO-AV socket, contact 1 or 3 Record (Normal Play). Play back this recording. Adjustment Procedure With F5603 (BIAS Frequ.) set the reading on the frequency counter to 70kHz ±10kHz. Set the voltage drop across R3600 with R3618 15mVrms. Check the frequency response.
(BIAS)
to
The voltage ratio of 400Hz to 8kHz must not be higher than 1:0.7 or 0.7:1 (±3dB). If the voltage ratio exceeds these limits, the bias must be altered: To increase the playback voltage at 8kHz: Reduce "BIAS". To reduce the playback voltage at 8kHz: Increase "BIAS". Remove the 270� resistor between IC7601-(10) and ground. Set output voltage with R3606 (PB-Lev.) to 0.5Vrms ±50mV.
2. Playback Level, R3606
