Here is the list I come up with after searching the web and getting all of your replies. Some people expressed an interest in the 6T9 tube and I think those are available cheaply from AES. There is probably lots missing from this list, especially many sweep-type compactron finals. 

For what it's worth, here it is. I will be going through my compactron pile and posting any that I don't need. I gathered them all together last night and probably have 200. But I don't recall seeing many of these types. 

Updates are always welcome.
