Michael DF2OK has been melting solder in Germany. Above is a short video of the first sounds made by an AC-1 replica he built. Michael notes: "Yeah, I love these old style radios. You can see nearly everything. :-) BTW: All without Arduino and other black boxes and chips!" FB Michael.
During the AC-1 build Michael struggled with a bad tube. His discovery and resolution of the problem is presented in this video (understandable even to those who don't speak German):
Finally, here is a nice video of Michael's 40 meter regen receiver. Anyone who has built or worked with a regen will understand perfectly this video. Watch Michael tune in stations while adjusting the regeneration. Note his demonstration of the lack of hand capacitance. FB Michael! Thanks!
