Back in the late 60's, I built a one tube superhet from a magazine called
Elementary Electronics. I still have that radio but not the magazine. Can
anyone tell me what month and year had that project? The circuit uses a
6M11
compactron and a 1N34 detector.

WA2ISE has a site that describes interesting mods to "All-American 5" AM
radios, and the following URL discusses a 3 Compactron set. By changing the
rectifier and detector to solid state devices, and either sacrificing IF
gain and/or speaker output, it might be possible to squeeze all that into
two triodes and a pentode, which is what's in a 6M11. It's not exactly what
you're looking for, but it may give you or somebody else some clever ideas:

Receiver - All Bands" article in "Popular Electronics" magazine. This may
be the article to which he refers:
