    Hey Guys, I have a set of EL34 tubes that are marked Dynaco Gt Britain. They do not appear to be Mullard and have a code 922-107 on them and have a brown base with two halo getters. Were these made by Tesla?

    all of the original Dynaco tubes I've seen with "made in Great Britain" are indeed Mullards, and some even still have the XF2 code on them
    Tesla tubes are Czechoslovakia
