Shango066: He impressively resurrects radios and TV that have been left out in the desert for 60+ years and is the best at troubleshooting. I learned that exploring mines is a thing from this guy, definitely check out his mine explore videos.
David Tipton: he restores the electronics yes, but I'm impressed with the chassis restoration work. He uses a lot of modern tools, like 3d print replacement knobs or create new labels.
Electronics Old and New by M Caldeira: He restores European radios from his home in Madeira. He has a cool technique of tracing schematics.
D-lab Electronics: convert old radios into guitar amps!
Glasslinger: he makes his own vacuum tubes! I like his restorations of very early radios.
W2AEW: because at some point you need to learn how to use a smith chart to design complex impedance matching circuits..
It is astonishing how people perceive things.
