Huh. I used to have the hardest time. It's been
a while
since I've had to look. Perhaps the tube data sites have
gotten a lot better since 2006ish? For example, it took
me a full day back then to track down data on the 6C4,
but now it just pops up on Google (I had to search more
than I would have expected to find a decent datasheet
with curves, but it's there at least).
The worst part is that I didn't think that 2006 was that
long ago until I just did the math.
Well...yes, lots of things have changes in the past 6 or 7 years...
Anyway...6C4?...really? Data for that tube has been in damn near every
post-War tube databook ever published in the US!
