BBH what chassis is this?

[mclovin]

Does anyone know what chassis this is. No real issue info anywhere that I can see. I can't get the gun to work properly on the old BBH game without turning up the brightness on the flyback, but then I get the horizontal lines. Seems there is no happy medium and there doesn't appear to be brightness adjustment on the chassis that does anything.

colour cut off's and gains are on main chassis-use the cut off's as brightness and gains for contrast

Awesome. I tried messing with everything and I can not get the screen bright enough for the gun to work properly without raster lines from having the screen pot too high on the flyback. So I need to adjust the bias and gains to achieve better brightness and contrast while still achieving the correct colors? I'll give it a try.

yeah and these are difficult chassis to get right colour wise,as you adjust the cut offs it affects the gains so its a real labour of love getting these just right
