I found something interesting between these two TS tubes. The one on the left is my original tube that I got in the beginning. The one on the right is from TK. I also have 4 more that are still in their package from the $34.99 deal, that I haven't looked at yet.
You'll notice in the pic , that the getter posts are on opposite sides of each other. Maybe @rnros can chime in on if this is normal, or if I possibly have a fluke tube. I've been burning in the tube on the right from TK. I'm around the 75 hour mark and it has pulled ahead of my original in SQ. Seems more dimensional, with more float/air in the imaging. I'm not sure if the getter setup has anything to do with the SQ. It could very well be that the specs are better on TK's tube.
I'm curious if anyone else that has a few of these tubes, can find one with the getters opposite of each other and if they hear a difference between the two. The difference between my two in the pic isn't dramatic. But it's definitely noticeable when swapping between the two.
The getter post and ring only serve to hold the getter material until it is flashed onto the glass, after that it has no use.
You typically see getter assemblies vary, whether it be the full design, or just minor variations in the components. In this case, attached to opposite ends of the shield. BTW, the pair I have also have different getter post locations.
The difference in sound, my guess, is most likely due to tolerance variations, either in the components, or the full assembly. Or material variances, which I think less likely from closely dated units.
