I have the small o-getter, large o-getter and d-getter versions of the amperex 7316 short plates. They have excellent prat, but sound a little bright in my system. The mids are warm and clear. They are nice tubes, but not worth paying a premium for. I prefer the telefunken's 12au7's I purchased from Dr. Gilmore because they have a more balanced sound. The 7316's midrange is superior however.
The orange globe 7316's are a good beginner tube.
