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.

Perfect copy of the service manual. you can enlarge every page, and it comes up
with all details.

6.IF ADJUSTMENT (MW) Requirement Measuring equipment: Oscilloscope or Millivoltmeter Test point: TP8(Lch), TP9(Rch), GND Adjustment point: L802 (1) Adjust the setting of Standard Signal Generator (hereinafter S.S.G.) to 999kHz of 30% variation. (2) Adjust the receiving frequency of the main unit at 999kHz. (3) While looking at the waveform on the oscilloscope, reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). (4) Adjust L802 until the waveform of the oscilloscope reaches the maximum. 7.TRACKING ADJUSTMENT (MW) Requirement Measuring equipment: Millivoltmeter Test point: TP8(Lch), TP9(Rch), GND Adjustment point: L952, L953 (1) Adjust the S.S.G. setting to 999kHz of 30% variation and reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). (2) Adjust the reception frequency of the main unit to 999kHz. (3) Adjust L952 until the value of the millivoltmeter reaches the maximum. (4) Adjust the S.S.G. setting to 603kHz of 30% variation and reduce the output level all the way (till a certain degree of is monitored through the oscilloscope). (5) Adjust the reception frequency of the main unit to 603kHz. (6) Adjust L953 until the value of the milivoltmeter reaches the maximum. (7) Repeat the adjustment 2 or 3 times from step 1 to 6 above.
