Hi Kevin,
You said this >>
Don't you mean the 1930's? After all the 6L6 came out in 1936 I believe and it had beam forming plates from the beginning right?
Also, in my experience the 6973 doesn't sound anything like an EL84 and sounds closer to a 6V6 but maybe that's just me.
Also, I was wondering if you have heard of vacuum transistors? It's a development by NASA and the AMES research center among other places. I've been following the progress on these over the last 10 years or so, and they've recently figured out how to make them bi-polar, but the interesting thing that I found about them is that the curves looked like tubes/valves. I find myself wondering if these ever get produced somewhere if they can be used in audio to good effect. I can share some links if you want that I've collected about these over the years.
