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.
John Thompson, Newcastle Upon Tyne, England.
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.
ItΒ΄s very very nice manual with all, what i need. Original in good quality. Very fast business. Very much thanks...
3.2 Mechanism compatibility adjustment Notes: â¢ Although compatibility adjustment is very important, it is not necessary to perform this as part of the normal servicing work. It will be required when you have replaced the A/C head, drum assembly or any part of the tape transport system. â¢ To prevent damaging the alignment tape in the compatibility adjustment, prepare a cassette tape (for self-recording/playback), perform a test on it by transporting it and making sure that the tape is not bent by the tape transport mechanisms such as in the guide rollers.(See Fig.3-2-2a.) 3.2.1 Tension pole position Notes: â¢ This adjustment must be performed every time the tension band is replaced.

(1) Play back the back tension cassette gauge (A). (2) Check that the indicated value on the left side gauge is within the specified value (G). (3) If the indicated value is not within the specified value (G), perform the adjustment in a following procedure.(See Fig.3-2-1a.) 1) Remove the top frame, cassette holder and side frames (L/R) all together. (See âsection 2 mecha-nismâ.) 2) Rotate the loading motor gear to move the control plate so that the triangular stamping to the left of the âPâ stamping is aligned with the stamping (a) on the main deck. This positioning is mode (B1). 3) Adjust by turning the adjustment pin so that the tip of the tension arm is aligned with the stamping (b) on the main deck. 4) Rotate the reel disk (S) by about one turn clockwise and make sure that the round hole of the adjustment pin is located in the âOKâ range. If it is outside this range, restart the adjustment from the beginning. After completion of the adjustment, rotate the loading gear motor to return it to the mode (B2) position.
(1) Play back the alignment tape (A1). (2) Apply the external trigger signal to D.FF (E), to observe the V.PB FM waveform at the measuring point (D). (3) Set the VCR to the manual tracking mode. (4) Make sure that there is no significant level drop of the V.PB FM waveform caused by the tracking operation, with its generally parallel and linear variation ensured. Perform the following adjustments when required. (See Fig. 3-2-2b.) (5) Reduce the V.PB FM waveform by the tracking operation. If a drop in level is found on the left side, turn the guide roller of the pole base assembly (supply side) with the roller driver to make the V.PB FM waveform linear. If a drop in level is on the right side, likewise turn the guide roller of the pole base assembly (take-up side) with the roller driver to make it linear. (See Fig. 3-2-2b.) (6) Make sure that the V.PB FM waveform varies in parallel and linearly with the tracking operation again. When required, perform fine-adjustment of the guide roller of the pole base assembly (supply or take-up side). (7) Unload the cassette tape once, play back the alignment tape (A1) again and confirm the V.PB FM waveform. (8) After adjustment, confirm that the tape wrinkling does not occur at the roller upper or lower limits. (See Fig. 3-2-2a.) [Perform adjustment step (9) only for the models equipped with SP mode and EP (or LP) mode.] (9) Repeat steps (1) to (8) by using the alignment tape (A2).
