5879 mutual/transfer characteristics

[Tonewood]

Does anyone know of a 5879 data sheet with a mutual or transfer characteristics graph that has several screen voltage curves on it? Using Merlin's or Kuehnel's methods, I would like to try other g2 voltages & draw the anode characteristics at different screen voltages.

I believe that I have checked all the sheets listed on Duncan's site. Did I miss it or is it possible that there isn't one?

Couldn't get the info from another good forum so I wanted to try here.

Thanks!

RCA & Tungsol is all that I could locate.

Thanks for the replies, but checking those sheets I don't see the transfer char graph.
The first graph at the following link is similar to the graph I want but this is for the ef86.
