Unfortunately I wasn't able to accomplish the goal of completing this amplifier in the time I had alotted. My plan was to build it up and take some THD measurements and show how to bias this (The F5 Class-A) amplifier designed by Nelson Pass. I ordered some sketchy JFETs from fleaBay and yup, sure enough they were fake, couldn't bias a damn thing. So I'll have to make a follow up video once I get the real JFETs in. Sorry folks, but at least it should be an interesting build!
