I have a bunch of LSK170 D. Is the designation D OK?

Any LTP you devise is going to have extra gain you will need to burn.
Since the channels are unity gain, they are going to gain match even if the device gains are different. The only issue I see is that there will be no additional CMRR, and it will not convert Balanced to single ended..
If your amps are balanced, great. if not, its worth a larger discussion.
World it be a possibility to get the gain down by degenerating (with resistors)? Gain of the LTP I mean.

Nice, you will need one NuTube per channel. It will to some degree drain the purse, but not much more so than purchasing 2SK246/389s and such. Some more space will be occupied by the NuTube of course, but, all in all, a splendid concept.

Ok,
This is embarrassing.
I was thinking of the unity gain buffer.
I don't think you are going to get a lot more gain with a LTP than a grounded cathode, depending on your load resistors.

I can't think of an effective way to lower the gain.
However there are a lot of smart people here.
Maybe they will have a thought.
