EV>When I first saw "12AX5s?" I was thinking about a tube such as a
EV>12AX7 which is a 9 pin minature tube.

EV>The 12AX5 wasn't in my 1976 A.R.R.L. Handbook, so I tried Searching
EV>to see what kind of tube it was.
EV>I gave up when none of the Results for the searches I did said anything
EV>for the 12AX5, all they were for were the 12AX7 tube.

EV>What size power output does a 12AX5 have?
EV>Who makes it?, Eimac, RCA, GE?

I could not also find out any Information on the 12AX5 but this guy has
soem unboxed ones.
