I update the R code that draws plots in http://ayumi.cava.jp/audio/quad/quad.html.
Please download it from the URL below.
I suppose that you are interested in push-pull load line, so the codes regarding visualization of the measurement results of the real circuit are not contained.
As for the code for another document, please wait a while.

Looking forward to try it in R. I followed your tutorial using CircuitMaker Student, and it worked fine. But I think doing it in R would be more elegant.
I found the codes that generated plots, but the tube models used in the documents are old, so the same plots could not be generated.
I will revise the documents, so please wait for a while.
DC Plate Voltage 1000V
DC Grid Voltage -61V
Peak AF Grid Voltage 56V
DC Plate Current 53mA
Load Resistance 7600Ω
2nd Harmonic Distortion 5%
Power Output 12W

Ayumi,
Thank you for replying again. I see now, so the book is not as analytical as the website. It looks like I better study up on the SPICE command line - more homework for me :-)
