Hep me identify this ECC83/12AX7.
Hello
I'm wondering what is this tube :
It's labeled Haltron, i had a Mullard i63 once, but here, no code.
The plate looks like a "Phillips group" one, but i never saw before a bridged getter in this type of tube.
I think i remember some early Mullard with bridge getters, but not with these very long rods.

Found : it's a "Siemens" made in RDA in the Lorenz plant and sold by RFT to Siemens, or directly to Haltron -as they often sold relabeled RFT- but the stamped square piece of metal was a "Siemens" feature.
