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.

7. GENERAL INFORMATION
7.1 SINGLE OPERATION METHOD
Single operation method and inputlevel.
The procedure and the input level of a single operation are shown below. 1. R85 are shorted by 1k�. 2. A point of the figure below in four places is connected. GND is not common because it is independent with chassis GND (GND of the amplifier), B1GND, B2GND, and B3GND. The potential of B1GND, B2GND, and B3GND is done by connecting A point in four places as well as chassis GND. 2. The power supply of the product is turned on. 3. the terminal CONT (2 pin of CN3332) are controlled respectively by the following voltages. CONT 5V ON ON
12V RY MUTE ON OFF
0V OFF ON
4. The signal of 10mV is input from input terminal (JA3333), and the output is confirmed with speaker terminal (CN3331). Note : If the music signal is input directly to input terminal (JA3333) with CD PLAYER etc. , the output becomes a large volume because there are 40dB GAIN of the amplifier.

Caution when disassemble. Even if the power supply code is pulled out from the outlet, neither C11 nor C12 of AF ASSY are discharged. Please discharge C11 and C12 of AF ASSY by the resistor of 100 � or more before removing AF ASSY or POWER SUPPLY ASSY. There is a possibility to destroy the transistor, and Please discharge by the resistor of 100 � or more.
