RE: Old stock Tungsol 6550s

Tung-Sol made three versions of the black plate: top getter only, top + one side, and top + two sides. If the two side getter tube is also a black plate, I wouldn't be particularly concerned. If, however, the second tube is a solid grey plate or a three hole grey plate, there will be some sonic differences but whether you would consider them "material" is difficult to tell.
