I Recently purchased yet another Service Manual from Owner-Manuals.com, this time for a Sony EVS700ES/UB Videocassette Recorder. The Manual was available for upload within two hours and is an Extremely Good copy, as some of this I was able to enlarge to get even better detail.
Once Again, Very happy with the result!
A good and useful manual. With these, We was abled to isolate and pin point the component that was causing the problem. The total time spent in troubleshooting is very much reduced.
Excellent service manual with all the necessary info. :)

T2 guide height adjustment (1) Turn the tracking control volume using a screwdriver so that the output level at the center of the envelope waveform is 80 % of the maximum output (waveform B shown in the figure).

(3) Check that tape runs in contact with the upper flange of the T2 guide. (4) Tighten the set screws on the upper flange to the following tightening torque. Tightening torque: 9 x 10_2 N.m (0.9 kgf.cm) 3. T2 guide height check Repeat the mode change from EJECT mode to PLAY mode 3 times.
