I saw an article in CQ for a one tube "peanut whistle" crystal controlled transmitter. 117N7GT tube, designed so that it didn't need a transformer or anything else.
I was young enough to not know better. I used a cardboard shoebox. All I had available at the time.
Damn thing worked, too.
However, nothing was soldered (my dad didn't trust me with a soldering iron then... well, at least not his, but he used them to create sculptures, not fix electronics, can you say "acid core solder"?) and my younger brother had to play with the wiring... first time I ever blew up some electrolytic capacitors.
One of these days, I need to find that schematic and rebuild that. I already have another tube, I do need to find a socket for it...
On Edit: A little research reminded me that the article I was referring to was called "The Peanut Whistle" and it was in the August 1965 issue of CQ. Never did find a copy of the article, though.
...and, no sooner do I post that, a quick search finds a copy on eBay for a couple of bills. I remember the issue now, it featured astronaut Owen Garriot W5LFL on the cover. Should have it in a couple of days...
