If NOS pre or power tubes became unavailable altogether, what new tubes would you buy?

Sophia Electronics are now carrying the 12AU7, 12AX7, EL34 and KT88.
I have not been able to find info on where they are manufactured or where they are sourced. Sophia does not answer my E-mails regarding theses questions. I can’t say whether they are good, bad or indifferent. The only Sophia tube I have owned was a 274B diode. It was a well worth purchase that made a very noticeable improvement in the SQ of a Woo headphone amplifier I once owned.

I have had excellent success with two tube-dealers.
McShane Designs for new, mostly Russian and European, knock-offs. Jim really puts the new tubes through a torture test before he ships. He also has a smattering of NOS tubes, but for Russian GL KT-88s, hard to beat.
For NOS, Andy Bowman at Vintage Tube Services is also very decent.

Dear @tubed1 : Jadis?, it's curious that you mentioned. When Jadis started in the audio market I had it in my system. Was the old times when Jadis was a not very reliable electronics, many people had trouble with their Jadis.

I don't know if you posted as a reference that today high price units used fancy caps/resistors or named as that price is what makes differences in quality level performance.

Anyway, Jadis does not makes differences for the better when we are comparing it against live MUSIC or SS alternative.

Dear @lewm : Could be obvious that the SS alternative using separate electronics is not the cup of tea and integrated amplifiers " out of question " but I heard from ML its integrated and we can’t say we are hearing an integrated unit instead separated.

I heard too the latest and top Devialet ( this is fully integrated phono to amp. ) and " even " that use digital overall technology I can say is something to listed carefully.

Today that exist a real mature in the SS " land ": mature designers, matured parts, matured design execution, etc, etc. and as Levinson ( I think Vitus and MBL and some other SS proponents as SimAudio. ) the integrated amps is something to " think seriously " about because has a lot of real advantages ( other than lower price. ) in favor of MUSIC quality level performance against separated ones and due to that matured SS industry I don’t see a real drawbacks that can goes against quality level.

Whay am I saying?: SS phono-integrated amps can " catapult " at higher levels never achieved the listen quality of our beloved analog experience.

What do you think about? is it a bad idea?

Btw, I listened the Diavelet in Guillermo's system, he owns the big/top Soundlabs speakers/subs and Magico too. I listened on both.

Regards and enjoy the MUSIC not DISTORTIONS,

For crying out loud, @rauliruegas all the poor guy asked for was advice on tube availability. It’s like he walked into the hardware store looking for a couple of lockwashers and you’re trying to sell him a boat. Get off your high horse!
