In response to your request a few days ago, I uploaded printscreens of my attempts to find your ZIP file.? Photos are in Photos > "Screen shots from Adrian's website".
On 7 November you provided this link:??which you said was for a zip file of your triode models.? "AdrianPage1.png" is what I see when I go to that link.? The link itself doesn't go to the zip file, and I don't see a link on that page to the zip file.
If I click on "... for vacuum tubes" near the top, I get to this page: "AdrianPage2.png".? Both the German and English have a "link" near the top.? But that link doesn't go to the zip file either.? It goes to only a PDF file, which is shown in "AdrianPage3.png".
So if I go back again to the previous page, and scroll down and down, there are SPICE Netlists, and graphs.? I did not see anything about a zip file.? I did see six links to subcircuits for six different triodes.? I thought that was all there was.
However, if I actually search that page for "zip", indeed it is there!? Until today, I did not see that.? ("AdrianPage4.png")? There was so much other stuff on that page, that I went right past it and did not see it.? It is about a third of the way (about 6 screenfuls) down a very long webpage.
So, you are correct that the link to the zip file is there -- but it was almost impossible to find it until I used my web browser's Search (ctrl-F).
Normally I am not a big fan of making things so obvious that they jump out at you.? However this was a case of the opposite, where it was almost hidden.
