A while back there was a 12v tube thread.
I saw this:

advertized in September Scientific American. The ad (on the
builditplayit.com site) says it uses a "double triode" and
requires 8-AA batteries (nominally 12V).
I wonder if it is a 12V tube kit. Perhaps a 12AE7 or similar.
Anyone know?
Can't speak for the kit but I know some guys have successfully used a plain
old 12AT/AU/AX7 at 12 volts with acceptable results.

Yes, I've done this, too. Also, when I was a kid playing with this stuff,
I got a 1T4 to audio oscillate at 7 volts on the plate.
