Afrotechmods, GreatScott and old army electronics videos on Youtube. I also got some courses on Udemy when they were on sale. I didn't find one perfect source but after a while, I think I finally got it. What really made a difference was getting an Oscilloscope and Function Generator. I'm looking to add a bench power supply too.
