Hi Terry
12AX7 because it is the most readily available valve (aka tube) in the world today, and therefore one of the cheapest. Just about every guitar amplifier and studio mic preamplifier has to have at least two nowadays.
AM, why not? It sounds great, it’s easy to tune, and with nobody on the air 99% of the time, who needs to save bandwidth? Not hugely efficient, but QRP is all the rage, and guess what - homebrew is gaining popularity, if the project ain’t too complicated.
History, you know, repeats itself. Otherwise, what is the point of studying it?
Meanwhile, over this side of the pond, our “premier” radio construction magazine “Practical Wireless” awarded its £20 “Star Letter” prize to a tired argument as to why “antennas” should not be called “antennas” but “aerials”. The Editor responded with the point that “aerial” is not a noun, but (quote) “a verb”. Verb? It’s an adjective, actually (“an aerial conductor”). Thus, the Editor reveals he knows no basic grammar. I despair.

Well, at least it's for 80 or 40 Meters. Wait a minute, what's this about a 12AX7 mic preamp? Not CW? Wait, 7290 kilocycles per second. A new kind of SSB? No, it's Amplitude Modulation. AM???? Really?? (I know it's by Bob Heil, but how many hams are REALLY going to build this project?) Did someone find a huge warehouse of 12AX7s that they need to push? All of five Watts of AM, maybe the 6AG7 is the tube to unload.
