Not sure which flagship you're referring to but Susvara and Abyss owners have generally given intelligent feedback.

Not those, it does not matter.

Just purchased these Miniwatt EL34 metal base. I ask my supplier (and friend ) for a newer pair and I was given. According to @leftside, they are 4th generation of EL34 metal base.

Yes very nice. 1956 light brown lower base from Eindhoven. Single disc getter at top. Welded plates. Look in good shape. This was the last metal base version made. It went on for one more year to 1957.

Thanks, you're my source of information of these tubes. Perhaps you should start a thread on KT88, EL34, 6550, 6L6GC, EL156 etc. so we have somewhere to share.

You are lucky to own metal base, but I am not sure if those are exactly my type, I am not looking for the most laid back ones. Anyway, exactly when I said EL34 saga is over I found a pair of Sophia Electric EL34-ST. But these are, for sure, my last ones. I was very curious about them so I couldn't resist since they were not expensive.

They look nice isn't it? Now I will wait to receive and try them. Blue...

Leftside have you seen this link? http://www.tube-classics.de/TC/Tubes/Valvo EL34/EL34.htm

I examine my pair. One is SV1 and the other SV0. One is ultra rare and the other very rare.

Maybe I should. I managed to complete the KT61/KT63/KT66/KT77/KT88 with boxes collection this week.

Yes that is a great source of info. Note what he says about the DD versions.

I think there is a mistake on his site though. I believe “L” to be Brussels (and “X” is Sittard). I’ll double check later.

Your tubes are the 1956-1957 versions. He doesn’t even mention an SY1 for those (“1” is the batch code), so probably ultra ultra rare I think you mean “Y” and not “V”.

Do it. I know your collection will be superb. At this stage I'm only buying to use. If it comes with original boxes great. If not I'll still get it if it's in good condition.

I was paying so much attention to the metal base I didn't read about the DD versions but now I saw. I'm getting them next and after that the expensive KT88.

He did mention 56X/57/X SY0/1 so both mine are SY0 and SY1 in that category. Which means just very rare lol and not ultra rare. Well at the good price I buy it for, no complains. I did mention V instead of Y by mistake.

I also managed to identify my Miniwatt GZ34 metal base. It's TV1 56H. The 3rd one on that page. Again bought that from another friend for a give away price.

You have the Eindhoven 1956 metal base complete set! I also run the EL34/GZ34 metal base combo most of the time in my preamp. The silver metal bases matches the chrome finish of the chassis

Next try with Eternity will be 6p7s ( Russian octal 807) adapter is needed and should be done next week..
The tubes i have (Foton 1965) provide 20ma at 200V for a bias around -18V amplification factor is near 7.8. Measure quite well and have 3 matched pairs !

I will give my impression once tested.
@SonicTrance Thomas do you have any clue about good input tubes for this 6p7s with Eternity ?

// Today i use GU50 + EL11 listening "By Myself" album from Inger Maria Gundersen on HD650mod. Sound is very dynamic, clear with deep bass and light to wear !

 

[UntilThen]

807s are one of my fav tubes but I have so many favourites now lol. I'm using Tung Sol 6su7gty with Tung Sol 6550 from the 60s. A Tung Sol evening tonight !

Just use whatever input tubes you like. Remember, the input tubes doesn't drive anything in Eternity so it really doesn't matter. You should get the same "flavor" from say a Ken-Rad 6SN7 regardless of output tube chosen. The 6P7S is a great sounding tube though!

From the first try 6p7s is really a good sounding tube same league as KT66 with solid bass and sweet tone, highs are sot as clean as EL39 and not as dry nor punchy as GU50.
Coupling with (russian) 6C5G give a good sound listening Belcea quartet with T1 !

807 is ok in my books but I'd place quite a few tubes above it.
