ECE4448 L22: Common Cathode Large-Signal Analysis (Headroom) (Guitar Amplification and Effects)

Minor correction: There's a few places where I say 360 when I should have said 361. The numbers on the slides are correct.

0:00 -- Introduction
1:20 -- External load resistance
3:14 -- Simplifying load resistance
4:02 -- AC load line
9:38 -- A caveat
10:16 -- Small-signal analysis
10:39 -- Output voltage swings
12:51 -- Large signal gain
15:28 -- Alternate universe
17:53 -- Cathode degeneration
19:19 -- New AC load line
21:32 -- Improved headroom
22:41 -- New output voltage swings
23:23 -- New large signal gain
25:30 -- New alternate universe
27:21 -- Parting thoughts

I liked your honesty towards the end about not quite understanding the issue

Mesa amps are reknowned for being a repair tech’s nightmare. Some guys won’t even work on the Mark series amps
