Hi, Jim
I thought I might have found what you were looking for. But, then I
did more digging and the situation seems muddier. The 1968 ARRL
Handbook has a project called "The Junior 'Miser's Dream'". However,
it is a 5-tube superhet receiver. It was based on a May 1965 QST
article subtitled "A Description of the 'Miser's Dream'".
This receiver is also bandswitched, rather than using plug-in coils.
The Handbook project is described as using some of the principles of
the QST article, but with some simplifications and reduced cost.
Most of the information I have seen on regens and super regens use one
to four tubes, depending on whether they use an RF amp stage, solid
state rectifier and dual-function tubes, and whether or not a speaker
was driven. The 1956-1959 KnightKit Space Spanner, for example, used
a 35W4, 50C5, and a 12AT7; but, the 12AT7 is a dual-triode, so that's
actually 'four' tubes and a diode. I don't recall what the famous
Ocean Hopper had for a tube complement, even though my Elmer broke me
in by letting me borrow his for awhile back in the day.
An old RCA tube manual I have shows plans for a four tube regen. See
http://www.mines.uidaho.edu/~glowbugs/12at7_regen.html for a one
tube, plug-in coils, regen. Also, look at
http://www.hvinet.com/rjmattson/56noviceRcvr for a nice regen based
on a 1956 QST article.
This site is a treasure trove of info on old ham radios:

Earlier tonight (yesterday evening, rather!) I ran across AA7JC's site
at http://www.lotts.net/ken/ham/. He built a neat little regen, and
he has several mp3 files you can listen to of QSOs. Amazing clarity!
Well, I hope you find what you were looking for, and if you do, I'd be
interested as well. You can email direct, just leave out the **'s in
the address.

Hello...
Back in 1973, when I was in the process of getting my Novice license, I
built a simple tube receiver from a construction article that came from
a Boy Scout Merit Badge pamphlet on 'Radio'. The radio didn't work well
because I was young (16) and really didn't know what I was doing.
Recently, I have had a desire to rebuild that radio for sentimental
reasons and am trying to find that schematic. The problem is, I cannot
remember the name of the article. My belief is that the article was
originally published in QST around 1965 and was granted reprint
permission in the 'Radio' Boy Scout merit badge booklet.
Does anyone have any recollection of which reciever that I am referring
to. What I remember was that there were 5 tubes (I think) and used plug
in coils for changing bands. It also was a supre-regen type receiver.
If anyone could help me with optaining the schematic for this, It would
be most appreciated.
Thanks and a very happy new year...
Jim
