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.
