Just an FYI, I ordered 6 tubes from tubedepot last week, and he only had 4 in stock, so I took them. I got 4 different tubes, 3 similar, and the GE was quite a bit different.
In the second image I have the tubes facing the same direction according to their pins, but you can see how the getter is positioned way different on the GE compared to the other 3 tubes I got. It leaves the silver deposit on the front of the tube, compared the back on the other 3. I don't know how different these will sound from each other, but obviously they look different.
