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.

Purchased the manual that I was looking for at a great price and could download it easily.. Great service experience and for future purchases I plan to use the site.
Thank you very much

� Set the mode selector to FM BAND. � Connect the wiring as shown in Fig. 1.
Step No. Adjustment Title FM SG (1kHz, ± 75kHz dev.) Frequency (MHz) Level (dBµV) Reception Frequency Display Adjustment Location Specifications � Adjust L7 so that the voltaghe between TP8 (+) and TP9 (�) becomes 0V ± 50mV. � Check the waveform with the oscilloscope, and confirm so that the output level is about �11 ± 2dBV and THD is about 0.5 ± 0.1%. Confirm that the "TUNE" indicator in the LCD is turned on.

6.3.2 AM Tuner Section
� Set the mode selector to AM BAND. � Connect the wiring as shown in Fig. 1.
Step No. Vt 1 (Tuning Voltage Adjustment) Adjustment Title AM SG (400Hz, 30% Mod.) Frequency Level (kHz) (dBµV/m) 530 1700 � � Reception Frequency Display 530kHz 1700kHz Adjustment Location L2 � Specifications � Adjust L2 so that the voltage between TP6 (+) and TP7 (�) becomes 1.0V. � Set the reception frequency to 1700 kHz and confirm that the voltage is about 6.6V. 1. Connect an electrolytic capacitor of about 10µF to TP9 (TP9 side is +), and terminate with TP10 by a resistor of about 47k�. Connect the sweep input to the both ends of terminated resistor. 2. Adjust T1 so that the marker of 450kHz ± 3kHz becomes the same level (single-peak characteristic of IF becomes symmetrical). 3. Input 74dBµV from the SSG, confirm the waveform of output signal so that the output level is �27V ± 2dBV and THD is about 1 ± 0.5%. And confirm that the "TUNE" indicator in the LCD is turned on. Connect an oscilloscope to TP3 (L) and TP4 (R), and adjust L1 (600kHz) and TC1 (1400kHz) repeatedly so that the output level becomes maximum.
