talking about tele ecc801s, how do you compare the sound of early double oo getter with common one?

Basically it still sounds like a telefunken ecc801s, Pitch-black back ground,detailed picture.but also mixed with some philips copenhagen(I don't know)? normal 801s sounds a little thin,it doesn't.most impressive point is it makes music lively,normal 801s sounds a little mechanic.
it's so rare I don't know how many still remains in this planet,maybe less than 100 or 200? so put it on amp is a crime and makes me feel guity

I only put it on less than half hour.

let's just forget it.

Welded plates in 1956? quite strange, wrong codes?

the picure of this tube I saw in the web seems all coded R6, I have 1 also has a R6 code.maybe welded plates didn't only appears before 1953,valvo 6211 was made in 1960s but also with welded plates.I prefer of believing it was made in 1956.

I would feel guilty like you

if they do not sound very different than common ecc801s (you described these ones exactly as I hear it) it's better preserve these very scarce tubes.... who knows how many remains??

very few for sure!

This one without diamond bottom is code B fp 02=february 1954, so according to your B vp 02=august 1954 the diamond for Telefunken ecc81 was first introduced somewhere between march and august 1954

These Telefunken with no diamond mark with horizontal printed,one of them have more black top.

before 1954,telefunken seems hadn't found their best stracture of ecc81,so they change the stracture frequently.

Yes, they are the same but what surprised me is the Mitcham made them in 1958 ( R8C ) instead of Blackburn made in 1955( B5E ) and the B7x version were already change to ring getter.
