Here ´s a mod from my machinist to center the battery plate from transvideo to fit the RainbowHd :
He "spaced" the AB plate from the aluminum back with 3 small risers ,then moved the whole Ab plate to be centered with the monitor rods (see pic) the risers are there to clear the bnc connector for SDI IN . I am using a cinecoil bnc cable with 90' angle and it fits right under the plate .
Only downside is I have to take the plate off to unplug the bnc cable . I just leave it there . Xlr power in just clears even with a straight connector .
Now my monitor is much more balanced . Not a game changer but much nicer overall .
