pchapman 261 #2 February 15, 2017 My dad dealt with all sorts of tube technology, so I'll pass that klystron related 1957 advert on to him! Canada did end up with a lot of radar chains on its soil, largely US funded, to provide advance warning of the Russkies. There was the Pine Tree line, Mid-Canada Line, and DEW line. Although I'm oversimplifying history, each was kind of obsolete by the time it was finished and the next one further north was built at great expense Quote Share this post Link to post Share on other sites
muff528 3 #3 February 15, 2017 Then he might enjoy looking through the whole April 1, 1957 issue of "electronics". Downloadable here. ...Over 400 pages of a LOT of cool stuff from that era. I ran across the Varian ad and the picture just struck me funny, given the current debate. I have a modest collection of electronics components and some radio equipment from the Cold War era, including a couple of smaller klystrons, some radar magnetrons, and other stuff. Once in a while I'll look around on the internet for info, specs, etc. I was looking for an adv to try to ID a particular Sperry klystron oscillator (I think) when I found this pdf. I have a friend who is building a man-cave in the "steampunk" motif and it gave me the idea to do something similar with some of this stuff. Cold War Chic!.

muff528 3 #5 February 15, 2017 Well, not Canadians, per se ...but Canadian low-level bombers. To paraphrase General Turgidson: "...we must not allow a Freedom Fence gap!" Quote Share this post Link to post Share on other sites

Of course, the concept was to eventually be able to detect and shoot down incoming ballistic missiles from Russia. And where would the highly radioactive debris land? Why, Canada of course.

muff528 3 #9 February 20, 2017 This might interest your dad. The business end of a missile "command-destruct" transmitter ...resonant cavity and output tube. I think this particular type was used in the 60s and 70s by the Range Safety folks even during the Mercury through the Apollo programs. Maybe someone here knows for sure. Pretty sure they weren't actually needed for any manned launches, though. Also a picture of the RF power tube. I think it'll clean and polish up real nice and look pretty good on the mantle. :) Quote Share this post Link to post Share on other sites
