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 Procedures
Tuner
Test equipment: Sweep / Signal Generator, Distortion Meter, Oscilloscope, Digital Voltmeter Note: The frontend is a completely preadjusted module. Only the IF filter must be adjusted to the IF amplifier (Adjustment 4). The values of the tuning voltages are as follows: 87.5MHz = typ. 1,6V; 108MHz = typ. 8.0V.
Adjustment 1. AM IF
Preparation AM; Sweep Generator 450kHz to AM Aerial Input; Ue > 60dBµV; Oscilloscope to Testpoint TP5, IC502(-19).
Adjustment Procedure Adjust with T503 for Maximum.
2. AM Oscillator
AM, 1620kHz; Digital Voltmeter to Testpoint TP3. AM; Couple Signal Generator via Loop Antennas; Ue > 50dBµV; fmod = 1kHz; Oscilloscope to Loudspeaker Output. FM, 98.0MHz Signal Generator to FM Aerial Input; Ue = 20dBµV; fmod = 1kHz; Deviation = 75kHz; Distortion Meter to Loudspeaker Outputs. FM; Signal Generator to FM Aerial Input; Ue = 50dBµV; fmod = 19kHz; Oscilloscope to Loudspeaker Outputs.
Adjust with T501 for 8.0V ± 0.2V.
3. AM Band Pass
Adjust alternating with L502 at 558kHz and with VC501 at 1440kHz for AF Maximum.
4. FM IF
Adjust with IF Filter A (under the cover) for Distortion Minimum.
5. 19kHz Filter
Adjust with LPF501 (left channel) and with LPF502 (right channel) for AF Minimum.
CD
Test equipment: Digital Voltmeter
Adjustment DC Offset
Preparation Mode CD; Digital Voltmeter between TP9 and TP10.
Adjustment Procedure Adjust with VR701 for 0V ± 0.1V.
