He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap linear regulator IC, but for the low component count, it is actually pretty good.

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...
