This is a good quality scan of the Operation & Maintenance (Service) Manual for the PAL version of this high-band broadcast umatic, BVU-800P
All schematics and lineup procedures appear to be included in this one manual AFAICT.
The file size is just over 113 MB which gives an idea of the quality and number of pages.
All of the schematics, which contain some fairly small print, are easily readable when you zoom into the page.

Good quality, all schematics of few of models. There is also short form of user manual and regulation manual.
;
Perfect copy of the service manual. you can enlarge every page, and it comes up
with all details.

ADJUSTMENT OF TAPE DRIVE TRAIN
1. Tape run rough adjustment 1 Remove the cassette housing control assembly. 2 After shortcircuiting TP801 provided at the center (facing to the main PWB), plug in the power cord. 3 Check and adjust the position of the tension pole. (See page 16.) 4 Check and adjust the video search rewind back tension. (See page 15.) 5 Connect the oscilloscope to the test point for PB CHROMA envelope output (TP201). Set the synchronism of the oscilloscope to EXT. The PB CHROMA signal is to be triggered by the head switching pulse (TP201 pin 2). 6 Set the alignment tape (VROCPSV) to play. (Put a 500g weight on the cassette tape to prevent lift of cassette tape.)
Guide roller Cassette Tape
Notes: 1. Previously set the tracking control in the center position, and adjust the envelop waveform to maximum with X value adjustment nut. Thereby the tape run rough adjustment is facilitated. 2. Especially the outlet side envelope waveform must have higher flatness.
Figure 4-32. 2. Adjustment of A/C head height and azimuth 1 Perform the initial setting of A/C head position by the method stated in "Page 18 Replacement 3". 2 Connect the oscilloscope to the audio output terminal. 3 Using the alignment tape in which 1 kHz linear audio signal has been recorded, adjust the height screw so as to get max audio output. 4 Using the alignment tape in which 6 kHz linear audio signal has been recorded, adjust the azimuth screw so as to get max audio output. 5 Repeat the above adjustment steps 3 and 4 a couple of times. Finally take the step 4 again.

Figure 4-31. 7 Press the tracking button (+), (�) and change the envelope waveform from max to min and from min to max. At this time make sure that the envelope waveform changes nearly parallel. 8 Unless the envelope waveform changes nearly parallel, adjust the height of supply side and take-up side guide roller so that the envelope waveform changes nearly parallel. (For envelop adjustment procedure refer to Figure 4-35.) 9 Turn the tilt screw to remove the tape crease at the fixing guide flange. Play back the tape and check for tape crease at the fixing guide flange. (1) If there is no tape crease Turn the tilt screw clockwise so that tape crease appears once at the flange, and then return the tilt screw so that the crease disappears. (2) If there is tape crease Turn counterclockwise the tilt screw so that the tape crease disappears. (Reference) If the tilt screw is turned clockwise crease appears at the lower flange.
For X value adjustment Adjust the X value, turning the geartype screwdriver.
