They don't look anything like the usual dimple-top RFT/Siemens tubes.

And you're right - they look like JJs at first glance!

Whatever they are I'd take a rain-check on these and wait for some that are obviously manufactured at the RFT plant.

Langrex are legit, by the way. And they even mention that the origin of these is unknown, so they clearly realise they aren't the typical Siemens EL34.

I am with Paulster. Siemens never manufactured some tubes. They would have a manufacture make them and they would put their name on them. I got some Siemens 12ax7s recently at a guitar show (New in Siemens box)and they turned out to be rebranded chinese 12ax7s.

Thanks for the replies, I think nowadays everything on ebay has to be double checked.

I Have just seen these on ebay and was wondering if they were for real, or just relabeled jj el34.

Welded plates, dual halo getter, look like late 80's/early '90s Czechoslovakian tubes , probably from Tesla or maybe early JJ. Or could be rebranded Polish Telam tubes - they all used the same structure and parts.

Because i have siemens el34, and they look nothing like them.

Siemens has *never* produced EL34's for general distribution. All of their tubes were OEM'ed from various manufacturers, so there is no typical Siemens EL34.

Early models were sourced from Valvo or Telefunken.

In the 70's they used a number of Philips-sourced tubes (including some from Mullard Blackburn).

Then they switched to Eastern sources and mainly got their tubes from RFT, Tesla or Tungsram.

The last Siemens-branded EL34's were produced by EI in Serbia, a few came from Svetlana SED.

Yeah didn't Tesla switched to black bases and high domed tops around the mid eighties?
fwiw I have a pair of Siemens labeled EL34 made in Holland with light brown base and DD getter's. Codes are wiped off but guessing probably late fifties,early sixties?

I've got some '92s with brown bases and not so curved tops...

Like one of the tubes pictured here?

BTW, codes are acid-etched into the glass, you should be able to read them using a magnifier.

I do not believe that these tubes are Siemens, normally they should have the S&H (Siemens/Halske) logo and wings to cool the g1 like this one:
