[QuadList] GRASS VALLEY GROUP 3240 proc amp manual needd andinfo on how ...

I also don't think it will track a 1/2" deck. I remember from back in those
days that the older 940 & 940H procs would track the 1/2' and other
slanters better than the 3240. I may have some boards stashed away in my
garage somewhere.
