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.

The ARN-6 direction finding receiver used 24 volts on the plates of
12SN7 tubes. I wonder how well they would perform at 12 volts?
