Nothing too complex, two tubes or so. What I want to build is something
that looks like it's from a 1950's Cold War era post apocalyptic story.
I definitely want to use tubes, and I have some headphones from that
era as well. The receiver has to be able to drive the headphones. They
are NOT crystal headphones.

There are a PILE of simple tube circuits on
http://www.intio.or.jp/jf10zl/index.html .

Most of them use Japanese tubes (the site is in Japan, after allg) but
I would suggest in many cases you can figure out what U.S. tubes are
similar.

Fascinating, but I didn't see anything close to what I'm looking for.
Thanks anyway.

I would suggest this one ( http://www.intio.or.jp/jf10zl/17ew8.htm )
would be a good starting point. It should work with most standard
double-triodes (12AX7, 12AT7, 12AU7, 12SN7, etc.) or two single triodes.
(6C4, 6J5, etc.).

This one ( http://www.intio.or.jp/jf10zl/12au70v1.htm ) could also be
adapted - use more than 12 volts on the plates and put a ~5k:8-ohm
transformer in the plate of the second tube (instead of the R-C network)
and it should do what you're trying to do.
