The labels are pretty well gone on the tubes. There is no visable date code except on one of the Bogen it has the number 1022-210, and all say MADE IN GT. BRITAIN in small letters across the top of the tube.Two visable seems on the top of the tube and all 3 flash brightly when put into the tube tester.The tube glass, plate stucture, bottom wiring and getter are identcal to a BOGEN Mullard I have with a B2A1 code--the only difference is the tilt of the getter.And the sound of course.That is why I figured they were Mullards.
Neff I must disagree. I have a perfect pair of long-plate mullard with the double getter holder(B8L and B8J codes)and the Brimar CV4004 12ax7 and in my amp the Mullards I am describing smoke them.I like the Brimar and the long plate Mullard--just don't love them I guess. As allways in tubeland, different tubes suite different amps and different tasks. I use these as input tubes for a Rogue Stereo 90 power amp. In a pre-amp or phono-stage, the ranking of tubes could be different. However, a good tube is a good tube. Just might not be the BEST tube for a given application.
