Great value, good scan, just as expected, everything that you need.
;
Good scan, great price, but almost the same with the SV260 service manual.
;
This PDF is very comprehensive. It includes drawings, parts lists, schematics, pictures, PCB drawings, mechanical layouts, etc. for all three stackable equipment. The scans are good too. Easy to read and no smudges or black lines. I have no complaints. I will make this site my first stop for finding my service manuals.
 ;
This service manual includes drawings, schematics, exploded views, parts list, operating details, and more. Very good scans, very readable. The only thing that made it a 4 star rating was on approximately 4 scans only half of the page was scanned then the other half. I would have preferred the pages to be whole scans.

Good manual contains all it takes to update, repair,these types of mixers.Thanks.

2. Turn the adjustment screw and check output peaks. If the peaks do not match for L-CH and R-CH, turn the adjustment screw so that outputs match within 1dB of peak.
CD SECTION
Note:
L-CH peak Output level
within 1dB within 1dB
1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M� impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. S-curve Check Connection:

Procedure: 1. Connect an oscilloscope to test point JPO102 (FE1) and TP 117(VC) on the CD board. 2. Turn the power on. 3. Put the disc (YEDS-18) in and turned power switch on again and actuate the focus search. (actuate the focus search when disc table is moving in and out) 4. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2.4 ± 1 Vp-p.

4. After the adjustments, apply suitable locking compound to the pats adjusted. Adjustment Location: Playback Head (Deck A). Record/Playback/Erase Head (Deck B).

Note: � � Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. Take sweep time as long as possible and light up the brightness to obtain best waveform.
Checking Location: CD board (SIDE B) (See page 24.)
