Very usefull manual. From my point of view there are needs more clearables images.
;
Once again owner-manual.com has saved the day for me, and come through with the manual I need. I looked other places too, and couldn't find it anywhere. Thank You owner-manual.com!!! You're the BEST!
;
very good quality that can be magnified several times, and it remains readable.
For sure I will return next time the need for a service manual arise.
;
The service manual is really great - thanks to it I was able to install the laser unit and thus "save" my CD-player, which seemed to be impossible before I had the manual.
;
Downloaded the Service manual OK of the Technics Piano and have now repaired it and its going fine. Excellant; thank you for the fine servce. A.M
7. Check the level B of the oscilliscope's waveform and the A (DC voltage) of the center of the Traverse waveform. Confirm the following : A/B x 100 = less than ± 22%

2. Turned Power switch on. 3. Put the disc (YEDS-18) in to play the number five track. Confirm that reading on frequency counter is 4.3218MHz.
8. Press the REPEAT button. (The tracking servo and sledding servo are turned ON.) Confirm the C (DC voltage) is almost equal to the A (DC voltage) is step 7.

VIDEO SECTION
Frequency adjustment 1. Connect the frequency counter to check point of the VIDEO board. 2. Adjust CT401 of the VIDEO board so that the frequency counter read 13.5MHz ± 40Hz at STOP condition.
