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.
I've not seen that magazine nor that particular circuit, but I do have a
photocopy of "Project E10" (apparently from a set of projects?) with the
title "One-Compactron Receiver - All Bands" and a footnote "Reprinted by
permission of Popular Electronics magazine", but with NO citation.
FWIW, the particular compactron this article uses is a 6AF11, but it appears
to be a one-stage regenerative receiver followed by two stages of audio.
For such a small circuit, it shouldn't be too difficult to regenerate the
schematic; I did it once for an All-American Five.
