A while back there was a 12v tube thread.
I saw this:
http://www.thamesandkosmos.com/products/ra/ra2.html
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?
