    Hi all.

    Im a bit confused.

    I recently changed my tubes on my barco 800 g.

    Now i need to aline them . What ive read in the service manual i need to adjust the vertical board. Using the small tiny potts on the vertical board.
    (small card conected to the vertical board. )

    But this board is missing !!!! or was that not on the early ones ?

    my Barco is a 1990.

    the amplifierboard to the crt are also a bit diffrent , because they have a little tiny extra card atached to them aswell, seems to have something with the brightnes.

    Anyone have information on this rare bg 800 build. please help me !!

    Im stuck.

    Best regards Stargatefour

    _____________________________

    Turned out to be normal, on my B800 the realy early ones dont have the little card. Thanks Curt Palme.

    My runtime is 25000 h....

    Have changed all tubes for new condition tubes , the blue is actualy new from box.

    What can i say, picture is realy nice.

    Having recently found those pots myself I might be able to help.

    There is a picture of the pots on this other thread that might be useful, they're not very big.

    On the first photo the Vertical board is the second from the top (on that photo) it's a double height board with an extra level attached via big brass poles. Between the two levels on the right hand side of the photo is a little board facing upwards. That's the one you're looking for. The second photo is a closeup of that little board, the pots to change the vertical position are the blue ones with the brass screws. (The one with red paint on is for the Red tube, the other for blue)

    If yours really is different from that, then I'm sorry for wasting your time :)

    Your vertical adjustment is in the installation option.
    As you say it was not untill the later 800 and 801 that the brass adjusters became available.
