These are tubes I got in trade for some work. They are the original tubes from a Vox "Pacemaker" amp made back in the mid '60s:



Not sure if the EL84s or the rectifier are good, but the 12AX7s work!
My research tells me that these are Mullard tubes made in the Blackburn factory and are quite rare. There are not many references to Vox branded Mullards out there, but I'm 99% sure that is what these are.
Anyway, I like nice old tubes, thought others might get a kick out seeing them, too.
