When I have to use a 12AX7 I use the Amperex Bugle Boy. I currently have 4 in my George Wright Phono Preamp. Good stuff.

  1. The Amperex is also my favorite 12AX7. The truth is that, all of them from 50's to the early 70's are excellent. The label (bugle boy) means nothing. They are all great. Look for them labeled Fisher, Eico or any other white print label with Heerlen Holland codes. The orange label tubes are also excellent, but will sometimes have faded codes after about 65'.
