  This video is excellent. That is the first time in my life that I have ever heard a satisfactory explanation of the difference between resistance and impedance. Thank you so much. I'm learning so much about valve amplifiers just from watching your videos. I'm very grateful that you have taken the time, care, and planning to share your knowledge with us.

  I'm retired Industrial electrician and a ham radio operator for 40 Yrs but I learn something every time I watch your videos.  In a word, they are brilliant. Many thanks.

  This is by far the best explanation of resistance, reactance and impedance of AC and DC signals that I have encountered anywhere (Videos & Books)! Thank you Uncle Doug! You are the BEST!

  One of if not the best explanation of transformer theory on YouTube I’ve found yet.

  You explain things well enough that I (a math zero) have a chance, if I watch this over and over, of getting THE MATH! Thanks for your patience!

  No apologies for the math, you are actually better for providing.  Electrical engineer here who has worked on vacuum tube guitar amps for decades, and this truly helped me get into the deep level of what's going on.  Appreciate it!

  After 43 years on this earth, 15 of which I have been a professor of electrical and computer engineering, I finally understand what speaker impedance mismatch means. Thanks, Uncle Doug!

  The best explanation ever about the difference between resistance and impedance on YouTube.

  Very good video. I have only one criticism: Please do not apologize for the use of math nor for getting into the numbers involved in calculating these concepts. That is exactly what's wrong with our generation is that people have become afraid of (or at least disinterested in) anything that requires exertion of mental capacity. If someone wishes to become good at audio electronics engineering, they'd better get over any aversion they may have of numbers. So sincerely, please do not apologize.
