My EE classes focused on plotting the characteristic curves of vacuum tubes (late 50's). Semiconductors were left for us to learn on our own.
This was my first radio, followed with a Meissner kit using type 76 triodes in regen/audio amp combo. I also mistakenly said the crystal was germanium but it was certainly galena. http://tinyurl.com/knpukag 73, Ron AC7AC -----Original Message----- Yes it most probably was galena, not geranium (wrong spell check choice !), and the "crystal" was about 3/8" in diameter, and height, and maybe mounted in Woods Metal not lead. Many years later, it seems, my first experience with a semiconductor device, was with an IN34, crudely built (by today's standards) germanium diode. We didn't even have any semiconductor classes or training, in my EE curriculum, when I attended college. I finally learned about them later, in the excellent electronics training I got while in the military and working on guided missile R & D at White Sands Proving Grounds. That and my ham radio design experience, got me excellent engineering job offers when I got out of the service.
