Composite Characteristic Chart With R

12BY7A PP Composite

Thanks again for Ayumi’s pctube, I can now generate good-looking composite characteristic charts using R. I think this is an easier and better way than using SPICE. Since all the relevant tube data are already stored in the pctube program, it eliminates the need to build a full simulation circuit in SPICE, with multiple meters in order to generate the plots (although that was pretty clever also).

I am sure there are many, many more tasks that can be done with R, unfortunately, without the right sort of mind, I find it difficult to write these sub-routines, so I just have to rely on the smarts of people like Ayumi to come up with the proper codes…
