Tube plot curve graph info

[68strat]

68strat found a video and wanted to share. Ole guy tells it in an old school way. He makes it easy to understand. Plots from tube data sheet/s. I certainly learned from watching. ... Finally a clue.

Hope ya'll can dig it. I did! .. 30 miniutes long video.
Hope it helps someone and hope the ole dude that made the video don't mind me posting this here.
