@UntilThen, yes, you're right, this month I've hit the ground running as far as that's concerned, but I have to say that a lot of things are the cream of the crop.
And it actually goes up another notch, if not two.
About KT63 :
Langerex is being accommodating again and I've written to them and told them what's going on.
And I would try again with the KT63 if they can guarantee that this tube will work.
Since only one of the 2nd set worked, they wrote to me today and said that they would send me another pair that should fit and work.
The only thing is that there should be a small difference in height with the 3rd pair.
6BQ7A : Unfortunately there were small logistical problems and I won't receive them until tomorrow.
RCA 6550 :
These arrived undamaged from Denmark today.
The price for this pair was again a small theft, but I can live with it, the pair is brand new and unused.
My wife lent me 215€ to get them, that was the price for this beautiful pair including shipping.
After cleaning they look like this and are plugged into the Ultimate and run flawlessly.
@UntilThen maybe you can tell me which version these are from the photos.
There are 2 O getters on the side of the discs and another one on top.
A big
thank you

@David A Silva ,without his valuable tip I would not have this beautiful pair.
When I researched further I was able to find more details on how to get a pair of indirect TS 6550s without breaking the bank.
I have paired it with Vcap EZ80 Haltron,TS 6SL7 GT as an experiment.
Soundwise they are still a bit sharp at the top, probably because they are still new.
Midrange is very good, nice and forward, bass could be a bit better.
But as always, there is still room for improvement with driver tubes and playing time.
The instruments are great, I already like it when the drums or double bass are thumping away.
The sound seems a bit bright for the first time, hence the sharpness in the first hour
The TS6SL7 isn't played in yet either, and as is typical for TS I think they come out better after 100 hours.
But otherwise very happy with it for now.
Untilthen was right that Kt's, 6550 and EL 34 are not comparable, each genre sounds different, but different in its own way.
Time will tell which I prefer.
Is it worth it? For now yes, the EL34 SED are really the best value for money so far, even if they are still in the burn in phase I like them.
I haven't heard much KT88 Svetlana from St.Petersburg but I'm also very happy with them.
6550 Rca will show it, but the first impression is very good.
And all worth the money.
