    Mullard xf2 welded plates. Double o getters. The best there is!Well after the rare Xf1 fatbase and the rarer metal base 34's.
    Nice score.

    The Traynor amp YBA1A that I had in the late sixties had four 6CA7 Tubes in it. The Music Man 65 I had later also had two 6CA7 tubes in it. I noticed that back in those days, you could find both names on many of these tubes. I also noticed that real 6CA7's tended to be wider and shorter with the glass than true EL34's. Oddly, I tend to associate their sounds to this sizing also. To me real 6CA7's seem to sound somewhere between the sound of an EL34 and a 6L6. My guess is that the EL34 is the British take on the tube, while the 6CA7 was the American take on this type of tube. A few years ago when I brought my Traynor Custom Special amp to Buzz Bourak in Toronto for retubing, he told me that at the time 6CA7's were no longer available and asked me to choose between EL34's or he could make it work with 6L6's. I asked him what he suggested, and he said me what sound I liked more. I said EL34's, and that's what he put in. The EL34's in your photo look more EL34 than 6CA7 to me.

    That's because they ARE EL34s.

    Tube companies would often "double mark" tubes, back in the day, with the number of the electrically equivalent tube, in this case the "6CA7".

    I'm sure it's because they didn't want to lose sales to people who might not know that the tubes are electrically intherchangeable and probably wouldn't notice the different sonic properties.

    As always, Mike's right. You are always right aren't you Mike? ;) But yeah, EL-34=6CA7.
